To everyone in this thread and the other, do you remember how all the videos we seen before the second Machida fight looked like this? Then after the fight a bunch came out of him sparring with a Karate master in order to get more acclimated to Machida's style? I wouldn't be shocked if that was the case. Shogun us similar to Frank Mir, we never get footage of Frank training for a fight before the fight. He is very protective of footage of his gameplanning.
