Berto doesn't do that though, I saw Collazo hitting durign the clinch with the opposite hand way more than Berto and compubox was scoring those punches. I liked when Hopkins used to do that because he would still be landing sharp effective punches, when Collazo or Calzaghe do it, they are just slapping for points. Regardless like I said southpaw vs orthodox=a lot of clinches because they get tangled up, especially when both of them like to fight on the inside.
