Its not. 3 nature releases are Kekkei Tota.

Moegi and Guru Guru have Wood release but not Yang release.

Maybe he could have used Yang release after Wood release or alongside Wood Release to make it stronger but im sure someone would have noticed/mentioned if Wood Release was a combination of 3 different natures
