Is it this tutorial? https://patdavid.net/2013/11/getting-aro...masks.html
It is good to know how it works but there is a script to generate all the channels. You can use it to compare with your results.
However my guess. Are you successively subtracting the L channel selection from the previous or something else.
This is the L channel - from one of the RGB desaturated, and the D is the whole image selected minus the L selection. screenshot https://i.imgur.com/3eZ9RoL.jpg
Subtract again from the last resulting selection gives a DD channel. https://i.imgur.com/QajQEPd.jpg
