the doujinshis came before the commercial release (so the other way around compared to kitada ryouma). and it was because they were successful and the art looked good enough for a general manga, that this commercial series even came to be. and no, the author is hard-focusing on the commercial series cause she took some long-ass breaks between doujin releases due to her work on this. it took 1.5 years between the 3rd and 4th doujin chapter and now 2 fucking years between the 4th and 5th. the 6th one may come out after elder scrolls 6 and half life 3, who the fuck knows.
