On a side note:

This almost makes sense. We've only seen the sealing jutsu once (having not actually seen the 4th seal Kyuubi) and it sealed orochimaru's arms into the 3rd.

At the same time, we don't know whether or not you can seal something into someone else and get yourself killed by the god of death.

I think i just confused myself
Don't worry about it Ryllharu, most ppl here are confused themselves [img]i/expressions/face-icon-small-wink.gif[/img]
I suppose you could say that Naruto is the 4th's reincarnations, but that theory in my opinion comes from left field. As far as we know, the 3rd used the SAME jutsu as the 4th. So if we look at the two times this jutsu was used the only difference was that the Kyuubi A.) is a demon and B.) is much more powerful than any human. With that said, a plausible reason would be that 1.) the 4th did not have the power to complete the seal, or 2.) is because that demons cannot be killed.
So the 4th then decided to seal the Kyuubi on Naruto's tummy....errr I mean belly...gut...crap factory.
