Thing is, with Jinchuuriki, it's always pretty clear that there are, in fact, two separate consciousnesses within one body. It's never been the case with ET. That's why I think the soul, just like the body, gets replaced.

The Jinchuuriki dying due to Bijuu extraction might as well be due to the fact that it puts a huge strain on the body. After all, those with strong life force could survive it, their own souls weren't touched.

Or, perhaps you mean that the host is only alive in a physical sense? As in, they retain motor functions and all. In that case, I wouldn't say that it counts as being actually alive. They basically become zombies, husks controlled by someone else's soul.
