I am not sure if it is a good test position.
It is possible that g5 was not a mistake and the mistake was later.

Black has alternatives later in the game(for example 27...axb5 instead of the
better move 27...Bxb5).

It is a common mistake of humans to assum that a sacrifice was winning without
proof only because of the fact that the side who sacrificed won and it is
possible that Nxg5 is enough only for a draw like other moves.

It is also a common mistake of me to analyze chess positions instead of working
about more important things like Movei or maybe they are not more important.
