Frankly, I think the manga is completely right concerning Dust Release in how it was explained: Mu was stated to have passed the secrets of Dust Release to Onoki.


 * How I saw the explanation: A Kekkei Tota is a bloodline that can be passed down to one individual to another. Dust Release happens to require one to know and possess three basic natures. Thus, it can be concluded that one can learn the Dust Release, especially if they meet the requirements (Possessing the Earth, Fire, and Wind Releases), and possess the Know How to preform them and meet said requirements (Hand Signs, Hand Posture, Chakra, etc.).

Look at it this way: Hiden are SECRET, Kekkei Genkai are GENETIC, Kekkei Tota are SECRET and GENETIC.
