I think he is talking about having different planes, one for the main zone of the arena, and one for the outer one (where the floor is like an iron mesh) and those planes should work like the bridge in blade's edge arena, where, if you are feared on top of the bridge (plane 1) you don't fall from the edges onto the ground (which would be plane 2 for example). Same should apply to DS.
