good find, i suppose hes using his actual body at the moment, considering it took oro's actual dna to reconstitute himself, then he assimilated the more of his own chakras from kabuto, possibly to strengthen his current state. but what troubles me is why go through the whole process of body switching if he can just implant his chakras in random hosts, put them on ice, and have juugo/kabuto revive him with his own dna when required , as long as his mind/soul remained unsealed i dont see why this would be less convenient than trying to find a new body every 3 years, unless his body as it is cannot sustain itself for an extended period of time, which would make sense but beg to question when exactly will it reach its limit
