No...it doesn't mean that at all. The words invulnerable and immortal do not mean the same thing. Even in this case, a Dragon's physical form has always been shown to regenerate on it's own and be everlasting unless put into a sort of stasis, and even then they still speak. If the soul is no longer in the body however, which is the case, it's obviously alive because what made it alive is no longer there. That does not mean that the Dragon was not immortal prior to that.
