The "wave shape" is showing what areas are in day and where it's night, i.e. what areas are in sunlight right now. So, it will be covering different areas depending on the time of day that the picture is taken.
So to piece the total together. Ideally need three totally isolated views where only the U.S. then Europe then Asia are in day time. Not sure how feasible that is to get hold of.
