I’d say it most definitely is! Very interesting find.

Aha! So is it now Johnson-Hujita-Justin-Hatori axioms? JHJH is kind of 
symmetrical.

I’d generally agree with your summation of the points, however, there’s others

Do you happen to have a link to the publication?

Ps. Minor toot: I’m about to release a run of my new robotic origami kits: 
called oribokit :)
There will be some available for postage internationally. More info soon.
