If the game worked on last man standing the players who lost first would be forced to watch for a very long time a battle which they've already lost. Given this, many would probably just disconnect and from my understanding of Pokémon netplay, that would cause the battle to end.
Even if it was just in single player mode, all that would happen is that if you lose, you'd just quit the battle instead of watching it all the way through. Even worse, you'd be wathcing a very laggy fight go on for who knows how long.
