During is Vizard training, Ichigo surpressed his Inner Hollow so it couldn't possess him. The only reason it could in the Muramasa arc is because Zangetsu's presence was removed from his soul. When he went Uber Hollow on Ulquiorra, it was because his powers went berserk, then he more or less lost his hold over them. Its just odd that they would use the original Hollow form is all. It might be so they don't make him too powerful, but still.
