He didn't. Not a single move that Royd did while fighting Yama was the same as what the Juha Bach did after he showed up. Not to mention Yama cut a gash into the fakes arm before he even went into Bankai, AND Juha Bach blitzed Yama twice afterwards, which the fake never could do. Both instances show the fake had nowhere near the strength and speed as the real deal.
