I believe the implications were that once dead and back in the lifestream, souls do not immediately dissolve. Especially on the way to Hydaelyn, we encountered several souls that have been dead for a good while now (obviously not sure how much in universe time has passed, but certainly souls have been lingering there that we encountered in 2.0 at the very least).

Regarding those two, we don't know is probably the best answer here. We're not sure they actually split into 7 parts, and if so, there's just no information on if we reformed the 7 parts, pulled pieces or even created a "primal" version of them. We just don't know.
