But if that were the case, all characters would be both Yin and Yang Release users. Don't tell me not anyone can mold chakra to be 20% mental 80% physical thus Yang or 80% mental and 20% physical thus Yin for example. We were very early in the series told that different techniques use different ratios of physical and spiritual energies. So if your explanation were true, then all non-elemental chakra transforming techniques used by a character who is given Yin Release by Jin no Sho, but no Yang, would have to be all Yin Release.
