AP/ATHR kicking off in this case was obviously the direct consequence of an high speed prot, but without switching her to ALT. Those few seconds lagg seems to be due to turbulence action at the same point. But those A340 pilots applied also full thrust when autothrust disengaged, right after its auto-reduction from turbulences... and then, she goes from less than 70% N1 to 100%. Guess what, she climbed well! (with four engines TOGA). But, here also, nobody applied any stick imput until the top of it (about 30 seconds without a single imput).

what is with the g-protection in the time between ???
Pilots are quoted talking about Alternate law less than 10 sec. after AP & ATHR kicked off... where is the lagg?
This is not like recorded DFDR data that will confirm that it was simultaneous with those airspeed rejection (and, at least, the BEA should know it without any doubt at this point).
