I agree

Note that even if we have a rule that black need to be able to demonstrate
helpmate when black has a forced mate in 4 in order to win then black still wins
the position as the following composed game proves.

White can lose by checkmate even without blunders that allows the opponent mate
in 1, mate in 2 or mate in 3.
