In the Infinity Countdown Prime Loki also cut Logan to be sure, that he has a healing factor to distinguish Logan from 'pretenders' ! The Logan in The Hunt for Wolverine Mini bleed a lot !
So we are dealing with doppelgangers without a healing factor.
Or:
I think to remember that J.D.White stated a long time ago in on of the x-day Monday chats on twitter, that in the marvel universe one needs a soul to have a healing factor. So take this with a grain of salt please, because it was a time back. (And I do not know if this contradicts continuity)
So if I remember this correctly, this could mean soteira was able to resurrect logan's body without mind and soul and used him like a puppet, like seen in claws of a killer. And the mystery of Logan's resurrection Ch. Soule is talking about is how Logan's mind and soul found his way back to his body! Is it nightmare enough, if you wake up after your death in a bloodshed your own resurrected body created? This could mean that he was slowly finding himself again in the situation soteira created and went rogue on soteira.
Another strange thing is, that in the early shown Mc.Niven art, Logan is back in costume. If this happens in the first issue, this is strange if we assume that Logan was resurrected by Soteira. The only explanation I can think in this kind of scenario would be a surreal inner struggle to find himself again. There was a picture were Logan is shown in costume seeing himself as Weapon x in a mirror like situation. ( In the original Weapon x story by Barry Windsor Smith there happened a lot only in Logans mind, imo)

Or you can have always the doppelganger theory.
But as you stated it does not explain why his healing factor seems to be weakened again! And this seems to be the real Logan! Urgh!!!
Maybe Persephone is about to take something from Logan. Hence the 'This will all be over soon! speech after she took of her cloves. (our 'special food theorie' comes to mind!)
We do not know about Persepone's powers yet. Given that her name is connected with the realm of the dead but also with spring and therefore new life.
But it does not explain the hot claws! I am tending to the explanation that they are a failed control mechanism installed by soteira, since Ch,Soule stated it is based on comic science.
Marvel created more questions than answers and I like that, but I really hope that RoW will deliver. Cant wait!
