I mean, probably poor wording idk.
It wouldn’t make sense for a new being to form, Yu’lon is a Wild God after all, they also mention ‘‘reborn’’ in the Temple of the Jade Serpent
Also if you put it into perspective, say, you switched bodies with someone else, your mind is your old one but the body is different, you’re technically a different being. You’re no longer the old you (old body + old mind) you’re a new being (you + someone else’s body).
