See my post above. The point of that screenspace on the side would be to have buttons or HUD items that you can touch with your fingers. "But why use screenspace?" Because with a screen they can change the shape, orientiation, color, size, etc of the buttons. It really isn't far-fetched.
But you are still holding it like a controller, not a phone and part of your hands will cover the screen. Especially when you have large hands. It is an absolutely ridiculous design. If it is even real.
