Though they're not perfect. They said that one pilot is supposed to read the item, the other pilot say the answer, and the first pilot visually confirm it; but at 1:42, I noticed the first pilot say "emergency exit lights", hear the confirmation, and move to the next item without her eyes moving away from the list.
I'm not sure which of several possible conclusions to draw from that. ("Humans suck", "it is indeed staged", "the procedure has enough redundancy that the chance they're both careless on a given step is small", "the pilots feel that the emergency exit lights aren't particularly important", ...)
