Question is though when you desummon a body from usage does it mean that same sacrifice is reuseable or was a new one needed.

No he wasn't he was given an advanced body beyond his prime and the way to do that would mean a special sacrifice. Don't believe me check this out.

Another thing that also has to be considered is when exactly did kabuto consider madara as at his prime state and when were those cells gathered? Was it near the end of his life when he had time for the cells of hashirama in him to mature or was it during the battle of the valley of the end. Then there is also the possibility that these cells may have even been gathered much earlier during the ninja war prior his battle with hashirama. At this point we do not know when that exact prime is considered. What we do know is he has been brought back at full strength with a younger body, his mind prior to his death, and a special version of the edo that seems to be more advanced than the standard edo. Hell it took extra chakra just to summon him.

Again its still theory at this point but it begs the question of what exactly has happened to yamoto since he was in akatsuki hands. My guess is that he has been used as an edo sacrifice.
