    Appeal from the United States District Court
    for the Middle District of Alabama
    _______________________
    (August 7, 2020)
    Before WILLIAM PRYOR, Chief Judge, GRANT, Circuit Judge, and ANTOON,*
    District Judge.
    WILLIAM PRYOR, Chief Judge:
    *
    Honorable John Antoon II, United States District Judge for the Middle District of Florida,
    sitting by designation.
    Case: 18-15251     Date Filed: 08/07/2020   Page: 2 of 20
    This appeal requires us to decide whether the district court erred by refusing
    to adjust Christopher Henry’s federal sentence for time served on a related state
    sentence. See United States Sentencing Guidelines Manual § 5G1.3(b)(1) (Nov.
    2016). The Sentencing Guidelines provide that a district court “shall adjust” a
    defendant’s sentence for time served on a related sentence if certain requirements
    are satisfied.
    Id. The parties have
    never disputed that the relevant requirements are
    satisfied, but the district court nonetheless refused to adjust Henry’s sentence. The
    government argues that because the Guidelines are advisory, see United States v.
    Booker, 
    543 U.S. 220
    , 245 (2005), the district court was not required to adjust
    Henry’s sentence. But our precedent establishes that an adjustment under section
    5G1.3(b)(1) of the Guidelines is mandatory when its requirements are satisfied,
    and our precedent is consistent with Booker. We vacate Henry’s sentence and
    remand for the district court to adjust his sentence as section 5G1.3(b)(1) requires.
    I. BACKGROUND
    In November 2016, Christopher Henry broke into a business in Covington
    County, Alabama, and stole eight firearms. Police arrested Henry a few days later.
    At the time of his burglary, Henry had a prior conviction for assault and 10 prior
    convictions for burglary. He pleaded guilty to burglary in the Covington County
    Circuit Court for his latest crime. In February 2017, that court sentenced Henry to
    20 years of imprisonment.
    2
    Case: 18-15251    Date Filed: 08/07/2020    Page: 3 of 20
    In November 2017, a federal grand jury indicted Henry on one count of
    being a felon in possession of a firearm, 18 U.S.C. § 922(g)(1), based on his theft
    of the firearms. In January 2018, while Henry was still serving his state sentence
    for burglary, the United States obtained a writ of habeas corpus ad prosequendum
    from the district court. The writ directed the Covington County Jail to deliver
    Henry to the United States Marshal for prosecution on the pending federal charge.
    After entering federal custody, Henry pleaded guilty to the felon-in-possession
    charge.
    A probation officer prepared a presentence investigation report using the
    2016 edition of the United States Sentencing Guidelines. The report assigned
    Henry a total offense level of 27 and a criminal history category of VI. Based on
    those calculations, Henry’s guideline range of imprisonment was 130 to 162
    months. But because the statutory maximum sentence for his crime was 10 years of
    imprisonment, see 18 U.S.C. § 924(a)(2), his guideline sentence became 120
    months of imprisonment, see U.S.S.G. § 5G1.1(a).
    At his sentencing hearing in November 2018, Henry relied on section
    5G1.3(b) of the Guidelines to request a downward adjustment of his sentence. He
    argued that the district court was required to adjust his sentence for the 24 months
    he had already served on his state sentence for burglary, which was relevant
    conduct to his federal firearm offense. See U.S.S.G. § 5G1.3(b)(1). Subtracting 24
    3
    Case: 18-15251    Date Filed: 08/07/2020   Page: 4 of 20
    months from his guideline sentence of 120 months of imprisonment would yield a
    sentence of 96 months of imprisonment. And Henry urged the district court to vary
    downward and sentence him to 60 months of imprisonment based on the statutory
    factors. See 18 U.S.C. § 3553(a). Henry also requested that his federal sentence run
    concurrently with his state sentence. See U.S.S.G. § 5G1.3(b)(2).
    The government “conceptually agree[d]” with Henry that his sentence
    should be adjusted for the 24 months he had already served on his state burglary
    sentence. But because Henry’s original guideline range of imprisonment was 130
    to 162 months, the government proposed that the district court subtract the 24
    months from that range to yield a new guideline range of 106 to 138 months. The
    government asked the district court to impose the statutory maximum sentence of
    120 months of imprisonment, near the middle of the new range it had calculated.
    The government also agreed with Henry that his federal and state sentences should
    run concurrently.
    The district court sentenced Henry to 108 months of imprisonment. Because
    of Henry’s many prior convictions for burglary, the court refused to impose a
    lower sentence. But it explained that Henry’s federal and state sentences would run
    concurrently because his state burglary conviction was relevant conduct to the
    federal offense. See U.S.S.G. § 5G1.3(b)(2).
    4
    Case: 18-15251     Date Filed: 08/07/2020    Page: 5 of 20
    Henry asked the district court to clarify whether it had adjusted his sentence
    by 24 months under section 5G1.3(b)(1). The district court responded, “No. I’m
    giving the sentence under all the circumstances. . . . [And] 108 [months of
    imprisonment] is my judgment of a fair sentence under all the circumstances in this
    case.”
    Henry objected to the sentence. He explained that section 5G1.3(b)(1)
    provides that a court “shall” adjust a defendant’s sentence based on an
    undischarged term of imprisonment for relevant conduct. The district court
    responded that “Congress gets to say ‘shall,’” but “[t]he Sentencing Commission
    doesn’t get to say ‘shall.’” It overruled Henry’s objection.
    II. STANDARD OF REVIEW
    We review an interpretation of the Sentencing Guidelines de novo. United
    States v. Whyte, 
    928 F.3d 1317
    , 1327 (11th Cir. 2019).
    III. DISCUSSION
    Section 5G1.3 of the Guidelines governs the “Imposition of a Sentence on a
    Defendant Subject to an Undischarged Term of Imprisonment.” U.S.S.G. § 5G1.3.
    Subsection (b)(1) of that guideline requires the district court to adjust a defendant’s
    sentence for time served on an earlier sentence if certain conditions are satisfied:
    (b)   If . . . a term of imprisonment resulted from another offense that
    is relevant conduct to the instant offense of conviction . . . , the
    sentence for the instant offense shall be imposed as follows:
    5
    Case: 18-15251     Date Filed: 08/07/2020   Page: 6 of 20
    (1)     the court shall adjust the sentence for any period of
    imprisonment already served on the undischarged term
    of imprisonment if the court determines that such
    period of imprisonment will not be credited to the federal
    sentence by the Bureau of Prisons[.]
    Id. § 5G1.3(b)(1). This
    guideline uses mandatory language: it says that “the sentence . . . shall
    be imposed as follows” and that “the court shall adjust the sentence” if the relevant
    requirements are satisfied.
    Id. (emphases added); see
    also Antonin Scalia & Bryan
    A. Garner, Reading Law: The Interpretation of Legal Texts § 11, at 112 (2012)
    (“Mandatory words impose a duty; permissive words grant discretion.”). Our
    precedents hold that this language “renders the provision mandatory; a court must
    adjust a prisoner’s sentence when [the] requirements are satisfied.” United States v.
    Gonzalez-Murillo, 
    852 F.3d 1329
    , 1338 (11th Cir. 2017); see also United States v.
    Knight, 
    562 F.3d 1314
    , 1329 (11th Cir. 2009) (vacating a sentence because the
    district court failed to apply section 5G1.3(b)(1)).
    To trigger a mandatory adjustment under this guideline, four requirements
    must be satisfied. First, the defendant must have served a period of imprisonment
    for another offense. Second, that term of imprisonment must remain undischarged.
    Third, the other offense must be relevant conduct to the instant offense of
    conviction. And fourth, the Bureau of Prisons must not credit that period of
    6
    Case: 18-15251     Date Filed: 08/07/2020    Page: 7 of 20
    imprisonment to the defendant’s new sentence. U.S.S.G. § 5G1.3(b)(1); see also
    
    Gonzalez-Murillo, 852 F.3d at 1337
    .
    The parties have never disputed that the requirements were satisfied in
    Henry’s case. Henry had served 24 months in custody for his state burglary offense
    at the time of his federal sentencing—from November 2016 to November 2018.
    Although he entered federal custody in January 2018 through a writ of habeas
    corpus ad prosequendum, he continued to serve his state sentence as his federal
    proceedings progressed. See Vignera v. Att’y Gen., 
    455 F.2d 637
    , 637–38 (5th Cir.
    1972). The 20-year state sentence remains undischarged, and his theft of the eight
    firearms was relevant conduct to his federal felon-in-possession offense. See
    U.S.S.G. § 1B1.3(a)(1)(A). And finally, the parties agree that the Bureau of Prisons
    will not credit those 24 months to Henry’s federal sentence. By statute, the Bureau
    awards credit for prior custody if the time spent in official detention is not
    “credited against another sentence.” 18 U.S.C. § 3585(b). And the government
    does not dispute that Alabama will credit to Henry’s state sentence the 24 months
    he spent in official detention between his arrest by state authorities and his federal
    sentencing.
    A straightforward application of the guideline required the district court to
    adjust Henry’s sentence. But the district court refused to do so on the ground that
    “[t]he Sentencing Commission doesn’t get to say ‘shall.’” The government echoes
    7
    Case: 18-15251      Date Filed: 08/07/2020    Page: 8 of 20
    this proposition on appeal. It argues that because the Guidelines are advisory under
    Booker, the district court was free to vary from section 5G1.3(b)(1) based on the
    statutory sentencing factors. See 18 U.S.C. § 3553(a). We reject this argument
    because Booker did not render section 5G1.3(b)(1) advisory.
    The government resists the straightforward application of the mandatory
    language in section 5G1.3(b)(1) by invoking the well-established principle that the
    Guidelines are “advisory” under Booker. 
    See 543 U.S. at 245
    . If the Guidelines are
    advisory, the government contends, then section 5G1.3(b)(1) cannot have required
    the district court to adjust Henry’s sentence. After all, it is hornbook law in the
    post-Booker era that after considering the Guidelines and the statutory sentencing
    factors, district courts may impose any appropriate sentence “within statutory
    limits,” subject only to “appellate review for reasonableness.” Pepper v. United
    States, 
    562 U.S. 476
    , 490 (2011) (internal quotation marks omitted).
    To be sure, post-Booker references to the “advisory” Guidelines are
    ubiquitous in judicial opinions. See, e.g., Kimbrough v. United States, 
    552 U.S. 85
    ,
    91 (2007) (“[U]nder Booker, the cocaine Guidelines, like all other Guidelines, are
    advisory only.”). Indeed, “[v]irtually all of us are in the habit of distinguishing, in
    one way or another, between the ‘mandatory Guidelines’ that operated before
    Booker and the ‘advisory Guidelines’ that have operated since.” Lester v. United
    States, 
    921 F.3d 1306
    , 1312 (11th Cir. 2019) (W. Pryor, J., respecting the denial of
    8
    Case: 18-15251   Date Filed: 08/07/2020    Page: 9 of 20
    rehearing en banc). But sometimes idioms that are accurate in one respect “may be
    erroneous or inadequate in other respects.”
    Id. The maxim “advisory
    Guidelines” is
    no exception.
    Mandatory application of section 5G1.3(b)(1) would have further limited the
    permissible sentences for Henry beyond those permitted by his statutory range.
    After the district court considered the Guidelines and the statutory factors, it
    imposed a sentence of 108 months of imprisonment—well below the 120-month
    statutory maximum. But a mandatory adjustment for the 24 months Henry had
    already served on his state burglary sentence would have required an even lower
    sentence. At most, the district court could have sentenced Henry to 96 months of
    imprisonment—the statutory maximum sentence of 120 months adjusted
    downward by 24 months.
    According to the government, this result would contravene the advisory
    Guidelines regime of Booker. Cf. United States v. Bangsengthong, 
    550 F.3d 681
    ,
    682 (7th Cir. 2008) (“Booker made all Guidelines advisory . . . .” (emphasis
    added)); United States v. De La Cruz, 
    897 F.3d 841
    , 846 (7th Cir. 2018) (“[T]he
    notion of a mandatory term in the advisory Guidelines requires . . . intellectual
    flexibility.”). We disagree. This argument misunderstands which aspects of the
    Guidelines Booker held advisory.
    9
    Case: 18-15251     Date Filed: 08/07/2020    Page: 10 of 20
    Booker involved a Sixth Amendment challenge to the practice of judges
    finding facts at sentencing that increased a defendant’s mandatory sentencing
    range under the 
    Guidelines. 543 U.S. at 226
    –27. The Court held that this practice
    violated the Sixth Amendment right to a jury trial.
    Id. at 227–29
    & n.1. To remedy
    the constitutional violation, a separate majority of the Court held invalid the
    provision of federal law, 18 U.S.C. § 3553(b)(1), that made the sentencing range
    produced by the Guidelines binding on the sentencing court. 
    Booker, 543 U.S. at 245
    . The Court also invalidated the provision that mandated de novo appellate
    review of departures from the guideline range, 18 U.S.C. § 3742(e). 
    Booker, 543 U.S. at 259
    . And because the Court determined that making the guideline range
    mandatory in some cases and advisory in others would be contrary to the intent of
    Congress, it held that the guideline range is always advisory—even when
    mandatory application of the guideline range would not violate the Sixth
    Amendment.
    Id. at 266–67.
    Although Booker held the guideline range advisory, it did not make every
    provision of the Guidelines optional. Both before and after Booker, sentencing
    requirements in the Guidelines that neither enhance a defendant’s sentence based
    on judicial factfinding nor mandate the imposition of a sentence within the
    guideline range are binding on sentencing courts, so long as they do not conflict
    10
    Case: 18-15251      Date Filed: 08/07/2020   Page: 11 of 20
    with a federal statute or the Constitution. As explained below, a mandatory
    adjustment under section 5G1.3(b)(1) is one such requirement.
    To understand why some aspects of the Guidelines remain binding after
    Booker, it helps to review why all the Guidelines were ever considered binding in
    the first place. The Sentencing Guidelines “are the equivalent of legislative rules
    adopted by federal agencies.” Stinson v. United States, 
    508 U.S. 36
    , 45 (1993). The
    United States Sentencing Commission promulgates the Guidelines using the
    rulemaking procedures of the Administrative Procedure Act, see 28 U.S.C.
    § 994(x), which gives the Guidelines “the force and effect of law,” Perez v. Mortg.
    Bankers Ass’n, 
    575 U.S. 92
    , 96 (2015) (internal quotation marks omitted). As the
    Supreme Court explained in rejecting a constitutional challenge to the Sentencing
    Commission, “the Guidelines bind judges and courts in the exercise of their
    uncontested responsibility to pass sentence in criminal cases.” Mistretta v. United
    States, 
    488 U.S. 361
    , 391 (1989); see also
    id. at 413
    (Scalia, J., dissenting)
    (agreeing that the Guidelines “have the force and effect of laws”).
    The nature of the Guidelines as law is reflected in several provisions of the
    Sentencing Reform Act of 1984, Pub. L. No. 98-473, 98 Stat. 1987, which created
    the Sentencing Commission and empowered it to promulgate the Guidelines. As
    we all know, the Act purported to make the sentencing range produced by the
    Guidelines binding on the sentencing court, although Booker later held that it could
    11
    Case: 18-15251      Date Filed: 08/07/2020    Page: 12 of 20
    not do so. 18 U.S.C. § 3553(b)(1). But the Act also provided a right of appeal to
    both the defendant and the government if a sentence “was imposed as a result of an
    incorrect application of the sentencing guidelines.”
    Id. § 3742(a)(2), (b)(2).
    And it
    instructed the courts of appeals to “remand the case for further sentencing
    proceedings” if “the sentence was imposed . . . as a result of an incorrect
    application of the sentencing guidelines.”
    Id. § 3742(f)(1). Although
    Booker held
    invalid the provision that made the guideline range mandatory
    , id. § 3553(b)(1), it
    did not affect section 3742(f), which requires federal courts to correctly apply the
    Guidelines in all other respects. See United States v. Crawford, 
    407 F.3d 1174
    ,
    1178–79 (11th Cir. 2005).
    Because the Guidelines have the force and effect of law, sentencing courts
    may refuse to apply them only if they conflict with a higher source of law. Cf.
    
    Stinson, 508 U.S. at 38
    (holding that even the commentary to a guideline is binding
    unless it conflicts with the Constitution, a federal statute, or the guideline itself).
    Booker makes clear that, in the light of its constitutional holding, mandatory
    application of the guideline range would be inconsistent with the otherwise
    enforceable provisions of the Sentencing Reform Act. See 
    Lester, 921 F.3d at 1314
    –15 (W. Pryor, J., respecting the denial of rehearing en banc). For that reason,
    sentencing courts need not—indeed, they must not—treat the guideline range as
    mandatory. See United States v. Sarras, 
    575 F.3d 1191
    , 1219 (11th Cir. 2009).
    12
    Case: 18-15251     Date Filed: 08/07/2020   Page: 13 of 20
    Mandatory language in the Guidelines also must yield to any contrary instructions
    in other federal statutes. Compare U.S.S.G. § 5G1.2(c)–(d) (mandating that certain
    sentences “shall run concurrently”), with 18 U.S.C. § 3584(a)–(b) (giving
    sentencing courts discretion to run multiple terms of imprisonment “concurrently
    or consecutively” and instructing that they “shall consider” the section 3553(a)
    factors in making that determination); cf. United States v. Jarvis, 
    606 F.3d 552
    ,
    554 (8th Cir. 2010) (concluding that “the guidelines do not control whether
    sentences run concurrently or consecutively”). But Booker neither requires nor
    countenances district courts treating every “shall” in the Guidelines as a “may.”
    Absent a conflict with a higher source of federal law, sentencing courts must
    follow mandatory instructions in the Guidelines, which “bind [them] in the
    exercise of their uncontested responsibility to pass sentence in criminal cases.”
    
    Mistretta, 488 U.S. at 391
    .
    To determine whether section 5G1.3(b)(1) is mandatory under Booker, we
    must decide whether that provision affects the guideline range. If it does, then
    district courts may of course vary from the sentencing range that section
    5G1.3(b)(1) would provide based on the statutory sentencing factors. See Gall v.
    United States, 
    552 U.S. 38
    , 49–50 (2007). But if it does not, then Booker provides
    no basis to disregard the mandatory language of the guideline.
    13
    Case: 18-15251    Date Filed: 08/07/2020    Page: 14 of 20
    Section 5G1.3(b)(1) “does not reduce the defendant’s guideline range.”
    United States v. Helm, 
    891 F.3d 740
    , 743 (8th Cir. 2018) (emphasis and internal
    quotation marks omitted). It instead mandates a sentence reduction for certain
    defendants “after the court has determined the applicable range.”
    Id. (internal quotation marks
    omitted). This conclusion follows from the text of section 5G1.3,
    the structure of the Guidelines, and the commentary to section 5G1.3. See United
    States v. Lange, 
    862 F.3d 1290
    , 1294 (11th Cir. 2017) (explaining that the
    traditional rules of statutory interpretation govern our interpretation of the
    Guidelines).
    The text of section 5G1.3 makes clear that the guideline governs the
    imposition of a sentence, not the calculation of the guideline range. The title of that
    guideline is “Imposition of a Sentence on a Defendant Subject to an Undischarged
    Term of Imprisonment or Anticipated State Term of Imprisonment.” U.S.S.G.
    § 5G1.3 (emphasis added); see also Scalia & Garner, Reading Law § 35, at 221
    (“The title and headings are permissible indicators of meaning.”). Subsection (b) of
    the guideline provides instructions about how “the sentence for the instant offense
    shall be imposed” in certain circumstances, not how to calculate the guideline
    range. U.S.S.G. § 5G1.3(b) (emphasis added). And the guideline requires district
    courts to “adjust the sentence” imposed on a defendant, not the defendant’s
    guideline range.
    Id. § 5G1.3(b)(1) (emphasis
    added). In short, this guideline
    14
    Case: 18-15251     Date Filed: 08/07/2020    Page: 15 of 20
    mandates a sentence adjustment for a certain class of defendants; it has nothing to
    do with calculating a defendant’s guideline range.
    The structure of the Guidelines confirms that section 5G1.3(b) plays no role
    in calculating the guideline range. The Guidelines provide eight steps for
    determining “the kinds of sentence and the guideline range” to be used at
    sentencing.
    Id. § 1B1.1(a). The
    first five steps provide instructions for calculating a
    defendant’s offense level, and the sixth step explains how to determine the
    defendant’s criminal history category.
    Id. § 1B1.1(a)(1)–(6). Step
    seven then
    instructs the sentencing court to “[d]etermine the guideline range in Part A of
    Chapter Five that corresponds to the offense level and criminal history category
    determined above.”
    Id. § 1B1.1(a)(7). At
    that point, calculation of the guideline
    range is complete. See 
    Helm, 891 F.3d at 742
    . Finally, step eight instructs: “For the
    particular guideline range, determine from Parts B through G of Chapter Five the
    sentencing requirements and options related to probation, imprisonment,
    supervision conditions, fines, and restitution.” U.S.S.G. § 1B1.1(a)(8) (emphases
    added). Section 5G1.3, which appears in Part G of Chapter 5, is a “sentencing
    requirement[]” related to imprisonment.
    Id. And a sentencing
    court applies that
    requirement only when it “impose[s]” sentence
    , id. § 5G1.3(b)—that is,
    after it has
    calculated the guideline range, determined any sentencing requirements, and
    selected a sentence based on the statutory factors, see
    id. § 1B1.1(a)(7)–(8), (c).

    The commentary to section 5G1.3(b), which we must follow, see United
    States v. Burke, 
    863 F.3d 1355
    , 1358 (11th Cir. 2017), also makes clear that any
    adjustment under that guideline must occur after the district court has calculated
    the guideline range and determined the appropriate total punishment to impose.
    Application Note 2(D) gives an example of a defendant with a guideline range of
    12 to 18 months who has already served six months on a nine-month state sentence
    for an offense that was relevant conduct. See U.S.S.G. § 5G1.3 cmt. n.2(D). If
    “[t]he court determines that a sentence of 13 months provides the appropriate total
    punishment,” the application note explains, then the court should impose “a
    sentence of seven months, . . . to run concurrently with the three months remaining
    on the defendant’s state sentence.”
    Id. The seven-month sentence,
    adjusted for the
    6 months already served, achieves a total punishment of 13 months.
    Id. This example confirms
    that a district court must first determine the total appropriate
    punishment—up to the statutory maximum—and then adjust the sentence it
    imposes to account for time already served on the other sentence. See
    id. Because section 5G1.3(b)
    does not affect the guideline range, the authority
    to vary from the guideline range provides no basis to refuse to adjust a defendant’s
    sentence under that guideline. If the guideline applies, a district court may not
    refuse to adjust the sentence in order to further the statutory goals of sentencing,
    see 18 U.S.C. § 3553(a). The district court must instead select an appropriate
    16

    sentence after considering the guideline range and the statutory factors and then
    adjust the selected sentence to account for time served on the undischarged
    sentence for relevant conduct.
    We are unpersuaded by the contrary decisions of our sister circuits. See
    United States v. Carter, 
    652 F.3d 894
    , 896–97 (8th Cir. 2011); United States v.
    Armstead, 
    552 F.3d 769
    , 784 (9th Cir. 2008); United States v. Lane, 
    509 F.3d 771
    ,
    775–76 (6th Cir. 2007). These circuits reasoned that the refusal to adjust a
    defendant’s sentence under section 5G1.3(b)(1) may amount to a permissible
    “variance from the guidelines” based on the statutory sentencing factors. 
    Carter, 652 F.3d at 897
    ; accord 
    Armstead, 552 F.3d at 784
    ; 
    Lane, 509 F.3d at 775
    –76. But
    a variance from the guidelines refers to “a sentence imposed outside the applicable
    guideline range based upon the statutory sentencing factors found at 18 U.S.C.
    § 3553(a).” U.S. Sentencing Comm’n, Primer: Departures and Variances 1 (Mar.
    2020) (emphasis added); see also, e.g., Chavez-Meza v. United States, 
    138 S. Ct. 1959
    , 1963 (2018); 
    Pepper, 562 U.S. at 490
    ; Irizarry v. United States, 
    553 U.S. 708
    , 715 (2008); 
    Gall, 552 U.S. at 51
    . And as discussed, section 5G1.3(b)(1) does
    not affect the guideline range. So a refusal to apply that guideline cannot be
    evaluated as a “variance” from the guideline range.
    We acknowledge that our decision in 
    Gonzalez-Murillo, 852 F.3d at 1336
    –
    37, requires district courts to treat section 5G1.3(b)(1) as lowering a defendant’s
    17
    Case: 18-15251     Date Filed: 08/07/2020    Page: 18 of 20
    “guideline range” in one narrow circumstance: sentence-modification proceedings
    based on an amendment to the Guidelines, 18 U.S.C. § 3582(c)(2). In those
    proceedings, Gonzalez-Murillo held that courts must apply “all eight steps” of
    section 1B1.1(a)—including any adjustment under section 5G1.3(b)(1)—“to
    determine the amended guideline range” for purposes of a sentence 
    modification. 852 F.3d at 1336
    (emphasis added).
    The amended guideline range in a sentence-modification proceeding carries
    a significance that does not attach to the original guideline range. Unlike at
    sentencing, where the guideline range is advisory, a district court in a sentence-
    modification proceeding is forbidden to reduce the defendant’s sentence beneath
    “the minimum of the amended guideline range” except in one limited circumstance
    not relevant here. U.S.S.G. § 1B1.10(b)(2); see also Dillon v. United States, 
    560 U.S. 817
    , 819 (2010). Because Gonzalez-Murillo held that section 5G1.3(b)(1)
    applies in sentence-modification proceedings—even when it mandates a sentence
    lower than the guideline range produced by the first seven steps of section
    1B1.1(a)—it also had to hold that section 5G1.3(b)(1) lowers the defendant’s
    “amended guideline range for purposes of” a sentence-modification proceeding.
    
    See 852 F.3d at 1337
    , 1340 (emphasis added).
    Although we may have doubts about whether Gonzalez-Murillo was correct
    on this point, see 
    Helm, 891 F.3d at 743
    –44, the decision binds district courts to
    18
    Case: 18-15251     Date Filed: 08/07/2020   Page: 19 of 20
    treat section 5G1.3(b)(1) as lowering the amended guideline range that applies in a
    sentence-modification proceeding. But its holding extends only to the effect of
    section 5G1.3(b)(1) on “the amended guideline range for purposes of” a sentence-
    modification proceeding. 
    Gonzalez-Murillo, 852 F.3d at 1337
    . And we cannot
    extend its holding to the calculation of the original guideline range that applies at
    sentencing. As discussed, such an extension would be contrary to the text and
    structure of the Guidelines. It would also contravene Booker by making a
    mandatory guideline govern a defendant’s guideline range. And it would be
    inconsistent with our post-Booker decision in Knight, which held that section
    5G1.3(b)(1) is mandatory at sentencing and so necessarily decided that this
    guideline does not affect the guideline range. 
    See 562 F.3d at 1329
    .
    In sum, sentence adjustments under section 5G1.3(b)(1) remain mandatory
    after Booker. An adjustment for time served reduces a defendant’s sentence instead
    of enhancing it, so mandatory application of the guideline does not violate the
    Sixth Amendment. See 
    Booker, 543 U.S. at 244
    . And because this guideline has no
    impact on the guideline range, mandatory application of the guideline does not
    violate the remedial holding of Booker. Even when this guideline applies, the
    district court, consistent with Booker, remains free to select a sentence above or
    below the applicable guideline range. But after the district court has selected the
    appropriate sentence—whether above, below, or within the guideline range—it
    19
    Case: 18-15251     Date Filed: 08/07/2020      Page: 20 of 20
    must adjust that sentence for time served on an undischarged term of imprisonment
    if the requirements of section 5G1.3(b)(1) are satisfied.
    The district court erred by failing to adjust Henry’s sentence as section
    5G1.3(b)(1) requires. The maximum adjusted sentence the district court could have
    imposed consistent with section 5G1.3(b)(1) was 96 months of imprisonment—12
    months less than the 108-month sentence Henry received. For that reason, we
    reject the argument that the error was harmless. On remand, the district court
    should determine whether the requirements of section 5G1.3(b)(1) are satisfied
    and, if so, adjust Henry’s sentence accordingly.
    IV. CONCLUSION
    We VACATE Henry’s sentence and REMAND for resentencing.
