In any case in which benefits are reduced pursuant to the provisions of this subsection, the reduction shall be made after any deductions under this section and after any deductions under section 422(b) 1 of this title. Notwithstanding the preceding sentence, any reduction under this subsection in the case of an individual who is entitled to a benefit under subsection (b), (c), (d), (e), (f), (g), or (h) of section 402 of this title for any month on the basis of the same wages and self-employment income as another person—

(A) who also is entitled to a benefit under subsection (b), (c), (d), (e), (f), (g), or (h) of section 402 of this title for such month,

(B) who does not live in the same household as such individual, and

(C) whose benefit for such month is suspended (in whole or in part) pursuant to subsection (h)(3) of this section,

shall be made before the suspension under subsection (h)(3). Whenever a reduction is made under this subsection in the total of monthly benefits to which individuals are entitled for any month on the basis of the wages and self-employment income of an insured individual, each such benefit other than the old-age or disability insurance benefit shall be proportionately decreased.
