And if two people share an ability like Onoki and Mu having a Kekkei Tota then they can pass down or teach the techniques that use that ability it doesn't necessarily mean that Mu could have taught anyone the Dust Release Techniques.

After all just because Gaara taught Shinki how to use his Magnet release doesn't mean he could teach anyone Magnet release.
