I remain unconvinced the was center locked. We never see front and back simultaneously. The system, with the center locked, is pretty effective and predictable and should be reasonably yielding to analysis. When unlocked, the system is less predictable and more prone to odd behavior. Between the back-to-front-to-back flow of power, TRAC, and VSC, the interactions affecting operation when stuck have the potential to be pretty complicated. The behavior I saw didn't match perfectly with what I would expect unlocked, either, but since what I saw was seemingly odd behavior, I'll assume the vehicle was in its less predictable mode -- the one that's more likely to exhibit odd behavior in the first place.
