Probably not if there was visible fire, that tends to encourage even the tardy. In the Asiana case, I wonder how much of that cabin baggage was removed from the bins before the order to evacuate was given, now we've seen reports that the order was delayed?
As I said elsewhere, if someone is carrying some\thing (that isn't liable to damage the slide and is not otherwise slowing down the process) then it's faster to let them keep it than argue.
