The point is that it has a smaller footprint. While I think the flip is slightly dubious in utility the fold has undeniable utility in being able to fold. You gain a tablet sized screen that fits inside most pockets. I personally find that extremely compelling. Two screens doesn't achieve the same effect because it's two screens. Unless there's no bezel or physical gap (that you are going to feel any time you're using the device) then you can't utilize the size of the screen to its fullest potential. Microsoft's Duo phone does use two screens but it defeats the point of having one massive screen.
