C`mon, it's pure logic. Yin-Yang consists of simultaneous use of Yin (as spiritual energy) and Yang (as physical energy). Without any of these, it cannot be performed. Otherwise, it wouldn't be even called a Yin-Yang Release. It's the same case as with KKG natures, you'd fail to use a one if you don't possess one of the components.
