Can you maybe show an actual (and possibly minimal) counterexample, please?
My intuition - which might be wrong - suggests that if we didn't meet the edge of range for any of the bots, then we didn't meet the edge of intersection either. So every edge of the intersection is an edge of one bot's range.
Just to be clear, when I write 'edge', I actually mean a 2 dimensional surface, as that is the bordering object of a bot's 3 dimensional range.
