As I said in the talk page discussion, the very fact that it's possible that some medical ninjutsu might be Yin Release makes this case different from Rasa's. We can say for certain that Magnet Release is Wind + Earth, because there's no other possibility left. That's not the case for medical ninjutsu, with the Yin Seal existing.

Plus, if we consider the Yin Seal to be Yin Release, it would mean the databook effed up her profile anyway. But that just as a side note.
