And it is not a momentary confusion either, it is a persistent pitch up command. There were two other pilots there who did not react to this inconsistent action by the PF which makes it all the more puzzling
My emphasis added.
We do not know that the others didn't react, as the report does not tell us either way. The report does note, however, that the PF and PNF both did something a 2:13:28 (1 minute before impact), at which point the PF handed over control to the other. So there does seem to have been some reaction.
Edited to add emphasis.
