The way I was envisioning it is that the text box overlays the gameboard (like the current box giving the status of play), so you have a message as to what just happened (the game ended) rather than just being jerked out of the game screen to the end screen. It's more psychological than anything else. The way I see it, part of the problem is that the game ends abruptly and pulls you to a different screen. Even if the information is there in the post game screen, I have not caught up mentally, so the game feels somehow incomplete. But maybe its just me.
