When he gained Fullbring abilities after losing his Visored ones he fought in his human body. After Rukia stabbed him to regain his Shinigami powers his soul should have left his body but that wasn't the case.
What happened to him?

You're lookin for way too much logic.
He powered up (or down) and got a new costume to match. That was all that the writer was thinking about during that scene.
So You mean Kubo basically just dismissed that aspect of his power all together?
