The same reason why promotion to Rook is useful in FIDE Chess--on rare
occasions it is the only promotion that is any good. Let's say that in
the particular position promoting to Queen would cause stalemate--then if
promotong to Rook doesn't give stalemate but will allow you to win later,
it is the correct move.
These positions are not common, but they do exist.
