How to Fold Origami Quadruped Base

This video show how to create an origami quadruped base using instruction with a method called “Progressive Crease Patterns”. The quadruped base can be used as a starting point for designing a variety of 4-legged animals. One unique feature of this video is the use of a crease pattern that is duplicated for each step of the folding process and updated so that the sequence of the fold is tied directly to the crease pattern. One reason for doing this is that I frequently create SVG files that can be used on cutting/scoring machines to make a crease pattern that will be scored fore folding and wanted a system of visuals that will directly tie the correct folding sequence to scored crease pattern. A second reason is that I have attempted to fold from some crease patterns and struggle to find a good sequence to make the fold collapse in the correct way. I fist tried numbering the line on the crease fold but when direction of a fold on the same line changes, this is not sufficient.
I would like constructive criticism on the methodology of this video.
1. Is the approach new. If not who developed this approach and where can this approach be found?
2. Will a progressive set of crease patterns tie significantly help identify a critical folding sequence?
3. I recognize that progressive crease patterns require more time and effort than a single crease pattern, but maybe less effort than drawing standard origami diagrams. Is this true? Is the effort justified?
