Slimes spawns normally like other mobs. Slimes will spawn in swamp biome, flatland or anywhere if the game glitches out. Of course it will also spawn out of the slime spawers.
It's a bug. I think it's because the game spawns all slimes at one size, and then randomly selects a size to put there, regardless of space. For instance, the game might spawn all slimes as a two high square, and then randomly select a size of slime to put there. Something like that, but I doubt that's how it works.
