Mantisben,
This Duo Gang move is also in 18 Elders.
Originally it had a different name in that form.
I don’t have the book with me and I forget.
I think it was Left and Right Dodging Step.
WHF explains why he changed the name of this techinique in the 18 Elders form.
I think the HK 7* has a different application from how we learn it in Taiwan because I have seen HK 7* people do the move a little differently.
On the vidclips I posted it includes this specific technique so you can easily see if my app is the same as yours.

Humhom,
Young Mantis, I don´t know if we understand eachother right… can you please write in german?
(ok, my funny day today…)
What I meant to say: a technique should not limitated to just one possible application! But it´s the logik that tells you not to use bo choi against a bek choi!
I mean: when your opponent stads in left or right hill climbing stance and attacks you with a straight punch, you can apply bo choi in all that situations! But not in every situation!
I don´t like the limitated applications of some folks going: "ok, this will work if only my opponent stands left arr no I mean right and then punches with left… "
You know what I mean? Thats not a practicable fighting system!
If you want to throw your opponent its not necessary that he stands left or right in front: just grab and pull hard enough …

GBL,
Humhom? No idea what that means. Sorry can’t write in German. You want to try Chinese? 
I agree that a given technique can have mulitple applications…actually, I think multiple variations of a given application is more precise.

If I want to throw my opponent, I will use the throw that best suits that particular situation. Sometimes it won’t matter which leg my opponent has in front, sometimes it might. For example, if using the “dung pok” takedown, it doesn’t matter to me which leg the opponent has in front. He will just end up either face up or face down. But if using say the 7* stance waist chop for takedown, then if he has left foot forward, it would be better for me to use right 7* stance and vice versa so I may have to change stance but still same application. I would not “just grab and pull hard enough”. If I have to struggle to pull him for a throw, then I should be using some other technique.

Yes, you are right.
In that case you choose the best technique to work out the same result: throw the opponent.
I agree absolutely, that NOT every technique could work on both sides. But most of.
