Why would that be the case? I mean he lost his ability to transmute in exchange for his brother, if we assume like any attempt at Human Transmutation, the cost is an organ, in this case, it's the metaphysical ability to preform Alchemy for Al.

It's not like losing his ability should undo everything he's done with Alchemy, just cause he beat Truth once by giving up a ultimately unnecessary skill doesn't mean Truth isn't going to keep his previous winnings.
