It's just a money maker for the UFC. Dana White has very few big money fighters, plus there are only a few guys in each division that can challenge for the title. So he has to keep pitting certain guys against each other. If white was smart he'd have tito take a dive once in a while to keep the war going. Hell, they may as well have a tito-shamrock best of 7 and work it so it does go to 7. then let them slug it out for real.
