Why is it that a camera still has to focus after it is already in inifinity focus mode? For example, when a canon compact is set to infinity focus it can still prefocus. So what's the prefocussing for? To make sure that the object distance is far enough?

Is it because it still has to find the distance to focus on as it is not the hyperfocal distance?
