 Also, if Mifune's hitting herriman to the side, and Herriman's holding his sword out, Mifune would have to go under Herriman's arm and tackle him like that if he doesn't want to get stabbed. This would give Herriman plenty of opportunity to reverse the tackle, as Mifune would probably be distracted by having all of his fingers and nails broken at the same time.

 Mifune already knocked Herriman's sword and arm out of the way with his right hadn he is leading forward with the left handed strike.

edit: Also yes footwork is important in both a punch and a kick but lunging forward at someone and hitting them while airborn still carries a lot of power especially considering that it would be like running full speed then driving your hand like a spear into someone.
