If you watch the video, it's not just throwing the leg, there's also a behavior where they hold the legs in their mouth and slam it into the ocean as hard as they can by bending sideways. Considering dolphins use those muscles to swim, they are likely very strong, considerably stronger than human arms tenderizing meat with a mallet like we do. I don't see why you would think leaving the legs alone for ten minutes would be as effective as hammering them for ten minutes. What's going to bleed out and go lifeless quicker, an arm left alone or an arm being beat on?
