I mentioned that observation too, right after the patent hit the light of day.
There's actually quite a few mentions of bouncing around in the EMD update thread [webmasterworld.com] where people are redirecting to non-EMD domains.
I think "triggering events" like you suggest could definitely "be in play" for it though.
Maybe, when a site is currently penalized, when a redirect happens, significant changes to page titles, significant changes to a large number of pages at the same time, significant inbound link/anchor text changes, and things along those lines, so "minor changes in the wild" get ignored by it, but if there's a "threshold" hit over time or major changes they "check to see" why you're doing it?
Maybe we should break this off or start another one or something?
