Snap or not (since we have nothing better to do)

[Doug Cronkhite]

You're not going to get much pitch break since the aircraft is already
positively loaded, so reaching critical angle of attack requires much less
abrupt movement to get there.

To me.. this is absolutely a snap roll. The rate of rotation is not
constant. There is a definite autorotation going on.

Looks like a real tight and fast barrel roll.  Can't discern any pitch break

leading to autorotation.  Must have had some rudder in it, you can see an 
opposite kick at the end to get back on track.
