Professor Sage 'le Six Paths held the Ten-Tailed Beast in his holy stomach, which was much different than holding nine individual monsters. Besides, we don't even know if a Jinchuriki can hold more than
one Beast at a time.
Furthermore (and I keep repeating this), the other Beasts are sealed inside the Gedo Mazo.
The Gedo Mazo is too destructive and is awesomely over-powered. One shock-wave from it, and
boom! it'll rip Naruto a new Kyuubi-hole!
...so chaotic... so destructive... the Gedo Mazo...
I think I'm in love! D:
