Very cool form at the end! As for the reason why you slap your foot...i do not know, but somehow Pavel´s explanation makes a lot more sense to me than this.
You try to kick your own hand, because your hand serves as a pointer, thus your preload your muscles/tune your golgi-tendon organ/spindles and kick therefore higher as without the hand.
