That's strange, it does seem to for me. I will double check though. I had assumed the IR light goes on with in pocket detection so that it can see the reflected IR light in your pocket, thereby knowing when to turn the screen off. Regardless, this feature seems to be more of a pain than it's worth. It seems to turn the screen off too easily if your hand just brushes by it.
