Your understanding is quite correct. In the case that White King is not checkmated right now like above, the check pawn drop such as P*9b is definitely in a legal move. As Matsubara-san told, Checkmate by dropping a pawn is illegal in Shogi. But P*9b is different from Checkmate by dropping a pawn. Manabu Terao
