Heroes versus Villains falling problem

I can confirm that it is possible for the heroes to be alive on certain spots beneath the playing ground.

On Kashyyyk, this can be on multiple spots on branches. On Theed this happens at the bottom of the lightning room thing (were Darth Maul fought). On Hoth, a hero can fall down into the middle pit but still be alive.

Is it me or is the probability of staying alive higher for Maul than the other heroes? I have encountered Maul at the bottom of a pit more than any other hero.
