Bowline with Yosemite finish

Your video explaining the failure mode of the Bowline with 'Yosemite finish' is incorrect.

You have completely missed the key underlying issue!

The failure mode is induced by pulling on the tail before the core of the knot has been properly cinched tight.
It has nothing to do with the orientation of the tail as you claim... and your 'wrong-sided' Yosemite Bowline is in fact the correct orientation.

Summary of failure mode:
If you pull (yank) on the tail before the core of the knot is properly cinched tight - the tail will become 'displaced' to a position inside the nipping loop.

This failure mode can be induced in both orientations of the tail.
