When is a shawl and when is it a wrap

I have seen almost identical patterns that one called a wrap and one called a shawl. It is confusing

Are there guidelines for them or is it just what ever the designer wants to call it? Is it regional? I always considered shaped ones, like triangles and half circles, shawls and long rectangular ones wraps. Or any glittery fancy one worn in the evening an evening wrap.

I am working on a triple crochet Vstitch one in Twilight Satin Sparkle right now and truly don't know what to call it.
