Some who didn't learn the system in full went looking elsewhere for answers, often to other Southern CMAs, to see how similar terminology is used there and then fill their gaps and justify their methods. Saves face, they reckon.
And I'm certain this (LSDD in VT) has been explained to these guys a number of times here. Why do they still seem confused as if they've never had it spelled out before?
Explanations often get lost within the drama of long contentious threads. Seldom have either you or Guy simply just explained something without it having to be drawn out of you in an argument. So, thank you for the current straight-forward answer to the question. You see, I did learn both. I learned the one arm version as the best expression, but I also learned that it applied to both arms. I did not learn the 2nd half of the Kuen Kit that you mentioned, so thanks for that!
