You lose, you're no longer the champion and you'll have to face the Elite Four again for another shot at being the champion.
When you're not playing the mode, you're just always the champion and won't have any challengers. That way, you'll retain your freedom as the player. Wouldn't make much sense from a story perspective of course, but who cares?
