That's how I read it, though if it were my money I'd be carefully reading what subparagraph (A) was that they are ignoring.
I was thinking about that too.

I.R.C. § 36B(f)(2) Excess Advance Payments
I.R.C. § 36B(f)(2)(A) In General — If the advance payments to a taxpayer under section 1412 of the Patient Protection and Affordable Care Act for a taxable year exceed the credit allowed by this section (determined without regard to paragraph (1)), the tax imposed by this chapter for the taxable year shall be increased by the amount of such excess.
My comments - If the above does not apply it seems the rest is also not applicable.
I.R.C. § 36B(f)(2)(B) Limitation On Increase —
I.R.C. § 36B(f)(2)(B)(i) In General — In the case of a taxpayer whose household income is less than 400 percent of the poverty line for the size of the family involved for the taxable year, the amount of the increase under subparagraph (A) shall in no event exceed the applicable dollar amount determined in accordance with the following table (one-half of such amount in the case of a taxpayer whose tax is determined under section 1(c) for the taxable year):
If the household income (expressed as a percent of poverty line) is: The applicable dollar amount is:
Less than 200% $600
At least 200% but less than 300% $1,500
At least 300% but less than 400% $2,500.
I.R.C. § 36B(f)(2)(B)(ii) Indexing Of Amount — In the case of any calendar year beginning after 2014, each of the dollar amounts in the table contained under clause (i) shall be increased by an amount equal to—
I.R.C. § 36B(f)(2)(B)(ii)(I) — such dollar amount, multiplied by
I.R.C. § 36B(f)(2)(B)(ii)(II) — the cost-of-living adjustment determined under section 1(f)(3) for the calendar year, determined by substituting “calendar year 2013” for “calendar year 2016” in subparagraph (A)(ii) thereof.
If the amount of any increase under clause (i) is not a multiple of $50, such increase shall be rounded to the next lowest multiple of $50.
