I could say it's because he's has several 5 round fights but so has Dominic Cruz, and a ton of other guys have UFC fight resumes for years on end and somehow don't do it (Demian Maia over 7 yrs plus for example). Frankly, if referees don't punish guys they'll do it. It's not complicated math. Guy magically atop doing things even in the heat of a fight onxe points start getting deducted, it's weird how that works.
