The point that is missed here.....he is making a comment on the fact that the captain TELLS the copilot what to do, that the copilot is not really a sentient, independent expert, that can think and act on his own.
Rather he is just an extension of the captain, who will make all the decisions, take all the responsibility, and ultimately decide the fate of the aircraft that day.
Honestly, I think this is more of a statement about airline practices, of who is hired to sit right seat...a robot, just happy to be there, following what the capt tells him...or a redundent aviation captain/expert that actualy is there to provide a cushion of safety.
Under the premise in which he is referring, I have to actualy agree with him...your typical 'single pilot' airline captain, with some 400 hour Abinitio copilot, to watch, scold, instruct, is probably just better up there on his own.
