Seishitsuhenka is applied to already existing chakra, while Yin Release and Yang Release is basically normal chakra, just made up of either spiritual or physical energy. If you create chakra purely made of spiritual energy, the result is Yin chakra, which is released through Yin Release. It is still normal chakra without any kind of elemental nature, hence why it can't be used to create a new nature. If you can apply seishitsuhenka to that Yin chakra or not, is another story. I understand it. I was the one that updated the lead for the Yin-Yang Release article with the new info from the databook. And there is also a reason, besides the problems with genjutsu=Yin, why I still have "conjecture" tagged unto the omission of Yin for Hashirama and Nagato in the other thread. Yin and Yang Release is just as you explained them. And according to the nature chart and it's description in the opening pages of the databook, Yin and Yang are also chakra natures, and the self-evident meaning would be that Yin nature aligns with the ability to release only Yin (spiritual energy), and the same goes for Yang.

But my simple question still holds: Where does it say or show that Yin Release cannot be combined with elemental releases?
