That's assuming that he actually took the beasts out of the statue and put them back in the Jinchuuriki.

It's possible he's just using a technique to channel the tailed beasts chakra into their Jinchuuriki without actually removing them from the statue.

Still pretty confident Bee isn't going to make it out of this arc alive.
