I was testing weapon pickups and this old guy punched me, but I have never seen this set of animations. It's kinda buggy and he resets to his walking stance right after each attack. He swings his left arm from the side, then his right arm from the side. Most old NPCs I see just use the default attack animation.. the same as the player. He straightens his back before every attack and it jolts into the animation. The only attacks he has is a right hook and left hook. Nothing else, no 3 in a row power attack either. I've never seen this animation either... Come to think of it, how would I add a new fighting style?
