I never meant Kakashi's words about what a Kekkei Genkai is. A page earlier he explains that an advanced nature is created by controlling two elements simultaneously, using Yamato's Mokuton as an example: "He uses it together. By controling the nature of 'earth' and 'water' at the same time, he creates a new 'wood' element which he can then manipulate.". Yin and Yang are no elements and that is why they can't be used to create a new nature.

I've worked on this topic for a really long time, I've translated those words myself multiple times and I really know what I'm talking about here. If you still can't see it, I can't help you.
