It's as you said. Guenael was a figment - before Gremmy imagined him, he never existed. And now he doesn't exist at all. Everything he said and was only happened because Gremmy imagined him that way, so we can only assume that refers to his status as a Sternritter. There is no reason Yhwach's authority should refer to him.

Many people were under the impression that As Nodt was androgynous, having somewhat feminine facial features and an otherwise masculine body frame. The discussion was had to death so I am not really interested in having it again after it has already been resolved. BG9 is a somewhat more obvious case, since he (my personal opinion, mind you) is apparently a robot, making his gender difficult to identify.

Guenael wasn't even real. But BG9 is/was. That's really all there is to it.
