Well, I'm not sure he is throwing "bolo punches" ala Kid Gavilan or Louis "Feo" Rodriguez. They are rabbit punches when thet hit the back of an opponent's neck and are illigal. The ones to the back of a head are also " no-no's." Those are clubbing punches but tecnically are not rabbit punches. Bolo punches are perfectly legal as long as they are above the belt. Very few fighters use them becaus they take too much time. Naco Barrio is onethat does.
