There are no helpmates in K+R vs K+B where the bishop can win, your response seems to suggest otherwise.
It is indeed "explained" in the FAQ, but the only relevant part is:
"In rare cases this can be difficult to decide automatically (forced lines, fortresses). By default we always side with the player who did not run out of time."
Instead of making this clear, you mention FIDE rules, that actually support @TennisPlayer2 on this one (KR vs KB). Drawing rules are tricky, KR vs KN for example is already a different case.
