The photo is not related to the Orphee strings, just an example I found.

Well, Orphee strings look exactly the same as that picture, with the same number of twists and two more turns at the end. Picking up the half unravelled one from the trash, which I gave up after the first pitch shift before it failed, I see the string has been pulled through the knot, sliding within it and around the ball. A Pyramid string, in comparison, has a longer, tighter "loop" which looks as if the string has been compressed within itself. A Harley Benton string looks much like the Orphee but holds and so do others, including D'Addario. Orphee strings must be made of some strange, slippery metal, maybe softer? Or maybe harder, which would explain how the knot fails to grip. Strings need to stretch over their whole length. Double locking systems don't help.

I have no double locking system but I fail to see how windings would require stretching and not the rest of the string. What I have seen people say is that windings contribute to tuning instability. I suspect it is because that part of the string cannot be stretched as easily when it is pulled in the middle. The process then takes longer for the wound part.
If the metal is soft, the twisted string grips onto itself like a rope. The harder it is, the lesser it grips itself and it can slide. Crushing the knot certainly finalises such a grip. My Pyramid strings look like something of the sort was done.
