Its been reported that the PF (Bonin, the least experienced) was in the right seat and the PNF (Robert) in the left. Apparently Robert was woken up and then he swapped with Dubois while Bonin stayed in his seat. Presumably Dubois gave Bonin authority because he provided continuity when the crew changed.
Apparently it was Dubois worst executive decision ever. I could see letting Bonin Fly if Dubois stayed in the cockpit, but with weather approaching he should have handed the controls to the most experienced pilot.
Continuity? Who needs continuity...the A330 was flying itself...right
