This is an interesting case. What you have is an aircraft that in the event of an engine failure on take-off you have only seconds to feather an engine. On the other hand you have two pilots (presumably they were used to having two pilots in these situations). Engine failure is a likely event and it is an extremely dangerous one. So wouldn't you expect them to have a high-speed drill that tried to get input from both pilots albeit squeezed into a few seconds?
I think this is a failure to train and to embrace CRM.
I've said this before but I believe there is insufficient encouragement for non-flying pilots to veto the actions of the flying pilot in the event of emergencies. You can't tell me all those pilots on the Korean 747 didn't notice the plane was going onto its side.
