If white does not take the pawn at h7 then white is a pawn down after Rxb4 and
probably is going to lose the game.

Black has 2 connected passed pawn when white has no passed pawn after Rxb4

It is typical not only for computers but also for humans to take the pawn at h7
because humans hate to lose.

Not capturing the pawn means that you probably lose the game (you are a pawn
down when your opponent has 2 connected passed pawns).

Humans are not sure that capturing the pawn h7 is losing the bishop so they may
do it and hope that they will find a way to save the bishop
