u could be right, but right before the filler started when sasuke showed up late, and oro transfered to the new body there were still bandages on his hands. now I'm not saying your wrong, but it makes me wonder if the soul too would remain in oro's body after he transfers.
We'll if you remember, the only time we see Oro after transfering to his new body he doesn't just still have bandages on his arms, he has bandages all over his entire body. And what skin we can see on Oro's hands isn't grey anymore.

Azazel's right Oro only transfered early because he could no longer stand the pain in his arms or something (I guess that, with no soul in his arms, the flesh was starting to decompose). And after the big Sannin showdown he said that he had another way to restore his arms (by transfering).
