whats wrong with that?
the episode hasnt even shown any more than kyubi slashing the screen, so its too early to confirm nor deny that argument

besides, just as gaara's final form becomes stronger with the will of shukaku in control, maybe the body and chakra of kyubi is weaker without the will of kyubi in control
