The first two images, correspond to a familiar to me noose, which can be derived from the original post's structure, just by alternating the crossing knot's state component.
It is not the first time that is demonstrated, but this time as a genuine equivalent of the previous knot, with just nub manipulation.
I think one should focus to its anti-blocking system, where the returning eye leg component, " bites" its continuation, resulting to a manipulable, easy to loosen collar/nub at peak strains.
The third, equivalent, transformed, profile C, derivative, is generated by performing some additional collar flips to whichever of the previous profiles (third fourth image), which appears to be, so far, an original TIB, noose configuration.
