You're right - if you disable app reload you won't be able to exit that screen.
However if you disable app reload you have other problems since many apps don't have a way to exit except using the button. So if you do disable the button you would have to add some other method of going back (maybe a swipe, or double-tap with the accelerometer or similar).
So yes, ideally the app loader would have an option to not show it, but for the watch to be functional you'd need to add another way to go back anyway
