Call it whatever you wish, but in order to generate maximum acceleration at initiation, the top-hand must pull in the opposite direction the bottom-hand is being pulled.

His bat speed is generated late in this long swing (hands travel 40+ inches to contact). The bat-head would never lag behind the hands that far into the swing if the batter initiated the swing with good THT and applied BHT. He appears to me to have been fooled on the pitch and had to pull it.

Shawn,

Couldn't view the clip either. Would appreciate you trying again, please?
