I'm not addressing the validity of the "violent manoeuvre" (those Gs' doesn't look very different for both aircraft) but the fact that this 340 was, a priori, in an real overspeed situation (going close to Mach 0.89) in those turbulences. Then a pitch up seems to me appropriate, manual or automatic (and better in auto mode if those pilots were shaken enough as not being able to monitor their speed, already too fast at the first place). Calling it an "overspeed" incident, might be more adequate but sound much less dramatic than an "AoA incident".
My concern is more about how does this event could be qualified as an "AoA incident", while the main problem I can see here was a TCAS conflict between two aircraft flying in a very tiny turbulent airspace?
