That's actually exactly how it was designed in the Developer Preview, and for just that reason. Every time you pulled up the Start screen from with an app, the app would slide to the left as a hint it was available there. The problem was that the sliding animation just gave you a headache after a while, especially using the start screen from the desktop. So in the Consumer Preview it was replaced with a more subtle fade-ish animation, making it less apparent where the app went but protecting the user's long-term sanity.
