First of all, when you have watched this video, a number of things should be remarked:
Renske (tori in this video) is a highly-accomplished nidan kata judoka. We have chosen deliberately to create this video with a non-handicapped judoka so as not to distort the explanation with possibly strange moves or other nonessential contributions that a “true” handicapped judoka could make. Whilst this is by no means the normal way SNJF works, we felt that, in this case, proper instruction and execution is most important.
As stated in the video, this is by no means an alternative kata. The video merely shows all techniques that we have developed to surmount difficulties that our judoka encounter while performing a nage-nō-kata. Not all judoka have difficulties with all techniques.
