Ok. Follow me on this one. Madara claimed to have created them with YinYang. BZ revealed that Madara did not make them. If Madara did not make them, then they are not the result of the method he believed he used to create them. Whatever Madara claimed about the origin of White Zetsu was wrong. He was tricked into believing those things by Black Zetsu.

BZ and the databook explain that Madara had nothing to do with the creation of white Zetsu, and explained their true origins, which had nothing to do with YinYang.
