not quite, close, but the line your threading loops around the line that is not part of the loop in a bowline.
Dude was right
well, they really are slightly different, but they are functioning pretty much the same way.
i'm not a knot wizard, but i think the Best OSR knot pictured here is either mistakenly tied wrong way or we have some bowline knot variation.
they both don't tighten the loop.
i tested both of them at home and it seems like this Best OSR knot is easier to undo, which is not necessarily a good thing.
but there are real bowline knots on the original core bar photo (by aetos1986).
