I think A320 overwater configuration means that it's equipped with life vests instead of the seat cushions that float. They have 757s that are configured for overwater (Hawaii routes) and those that aren't, so perhaps this may be the explanation?</font>
They also have ETOP 757s, I don't think there's an ETOP A320/319.
