I actually think the idea that he summoned the Ten Tails' husk from within the moon and transformed it into the Gedo Statue at a later point might make the most sense, because it would explain the mechanism for summoning and synchronizing with it, as well as why it has such a particular form, with nine eyes and sealing properties.

It's probably just an unintentional retcon, though. Maybe it'll be clarified later.
