I guess this is sort of a matter of what is Black's best follow up move in a
way.  White HAS to either move the Bishop, or protect it, and it doesn't look
practical to protect it with it's King because it would either get the Bishop
pinned to it or maybe checked by Blk's Bishop.  Or Wht could protect the Bishop
with it's Rook, but that ties up the Rook.  But is BxP the best move.

But I'm not sure why it wouldn't be a good idea for Blk to trap the Bishop once
it's taken that pawn.

If it IS a better idea to take a pawn instead of trying to trap a Bishop, then I
agree with Chessmaster's capture of Rxg2 instead of what Comet has Blk doing,
Comet had Rxb4, but I believe that Black keeping it's Rook on it's 7th rank is a
better idea.
