Do not reset the ON_HOLD flag after processing the UP event.

Do not reset the ON_HOLD flag after processing the UP event.

It could be refer'ed by other callback called after UP event.
So it should not be cleared.

Instead of clearing them after UP event,
clear them right before feeding the DOWN event.

Update some comment style.
