I think he should have been DQ'd. The only reason i think that is because the illegal elbows are the ones that actullay finished the fight. If they didn't DQ him it would have sent the message that you can do illegal moves, as long as you finish the fight with them. If Hammill could have continued then they should have just taken a point. He missed with a few illegal elbows and you can here Mazzagati warning him then he connected with the two and thats when he stopped it.
