Referee Hector Afu isn't breaking up Smith vs Bauderlique...why?

[War Room]

Remember this guy was breaking up Kambo like as SOON as he got up on the inside. These guys are getting it on the inside and it's like Hector doesn't even exist.

How does a referee go from breaking two fighters up every 5 seconds to not doing it at all from fight to fight?

Hmm, I wonder why a referee would do that.
