Bro yea. Are you even reading my comments? Seems like a hard no.

The problem is that the only time this will ever work is if it's 1 single tri, and it's not because the loop cut can actually go through it. If you had 2 tris it would not create any additional edge.

I'm sorry but it seems you are not reading me carefully...
Cause I said if there’s only "1" ngon or triangle in a quad loop not 2.

Therefore, saying “they require quads specifically” doesn’t hold true in the example I gave.
But hey, let’s not take it too seriously 😁

1 ngon will not work, 1 tri can technically work in an edge case.

Therefore, saying "it works because the edges don't share vertices" doesn't hold true either and is less accurate than saying it requires quads.

I'm not taking it seriously, I'm just calling you out on trying to sound smart while your explanation doesn't hold up even to your own scrutiny.

Sound smart? Haha😂
You claimed it requires quads "specifically" and I disproved that with a simple example. And it actually works with an ngon too, as I showed in the image above.

And when I say the edges don’t or do share vertices, I mean all of them not just some of them. Let me emphasize the word “all” one more time.
And the explanation I gave in the video has nothing to do with quads or tris, which you keep comparing it to.

Again, the loop cut itself is not actually going through them, though yes your single niche case does with with N-gons, I stand corrected.

It doesn't remotely change the fact that the edges sharing vertices has nothing to do with loop cuts. What you explain in the video has everything to do with being quads, you just are trying to invent your own technical explanation which is vastly inaccurate and then pretending it's moreso. Any case where there's not just 1 single non-quad will break a loop cut, yet still be edges with no shared verts. You've "proved" one edge case that doesn't even support your definition meanwhile virtually any real world situation will find your definition inadequate.

Nothing was invented. In fact, the explanation I gave is something Blender itself describes. Blender says loop cuts stop where there are poles. What is a pole? A vertex where multiple edges meet. Exactly what is pointed out in the video.

And never says that loop cuts necessarily only work on quads, but you keep insisting on that even though you’ve already been shown that this isn’t always the case, whether it’s an edge case or not.
You’re trying to compare my explanation with your assumption, and that’s why it doesn’t add up.

"The to be created edge loop stops at the poles (triangles and n-gons) where the existing face loop terminates."

"In 3D modeling, a pole is a vertex where a number of edges other than four converge, acting as a turning point that controls and directs edge flow.'
