Dear Andreybhai, you state that there is only one moon dynasty. But Arjunbhai stated that Jagdamba is the moon of the seed-like world & Lekhraj Brahma is the moon of the base world. And both these worlds are different worlds having different moons. So both these worlds have different moon dynasties (if Arjunbhai's explanation is taken into account).
Again, the base world today is in the corporeal condition. Then how it receives light from the moon - Avyakt Brahma (who is not corporeal)?
