You've nailed it in the second part of your sentence. Once somethign lets go, it's anyones guess as to what goes next, what breaks and what tears off. You'd need a complex analysis and AI modelling to exactly re-create the chain of events. It could be wildly different every time. That video posted above is a perfect example of this. The blades hit, one loses the tail and the other tries to spin; add in 100 knots of airspeed and what happens next is anyones guess.
