No - The thrust levers were not moved according to the TRA traces P113 EN.
... around 2h 10min 17sec. It is here they recognize the THR/LK is active. I think shortly thereafter then they reset the thrust levers back to 100% N1 as depicted on the chart, my words.
Again, TRA traces don't show that. First time a thrust lever movement is recorded is just after
2h 10min 45sec
But, the thrust levers must have been quickly recycled out of and back into the CLB detent around
2h 10min 22sec in order to leave the THR LK situation (P108 EN), quickly enough that nothing has been recorded on the TRA traces. IMO.
