A few folks have made it clear the between pictorial instructions and reasonable intelligence: it should be completely reasonable to expect an emergency exit row passenger to open the door.

The vital requirement is that they do it at the right time, and even more: that they don't do it when instructed not to.

The over-wing exit might be undesirable, and opening it may be judged to risk spreading fire and fuel into the interior of the aircraft. In such a case it would be better that the person sitting there ignore the Latin roots for evacuate and the pictorial instructions, and instead stand and proceed to another exit, because they heard and understood the clear instructions to do so, given in a clear voice speaking English.
