This is an improvement as I see it. Many other GUI frameworks have this button behavior:
1) Press the button. Button selected.
2) Move finger out of the button. Button goes to normal state.
3) Move finger back over the button. Button gets selected again.
4) End touch. Button receives "click" event.
