No he is not the worst, not even close, and I did not get any sense he was full of shit either. It's just, this stuff has already been created and structure-mapped. It looks like he (or whoever he got it from) just tried to invent it out of an idea rather than any lineage or structure. He has an idea but no particular line of power (jin) going through the body at all. That being missing we could say "oh no big deal, hell find it" but he won't. The dedicated practice that does not have that is a detriment to even finding anything like that because it endlessly re-patterns the lack of it.This guy's been around for quite a while. I got the impression that he went to China or Taiwan, he got what he got, and just kind of does his thing. While I don't necessarily love his gongfu, he doesn't seem to be an outright bullshitter like a lot of the folks that come up.
I read it more as a devolution of technique that's easy to fall into as an art gets further and further from actual fighting usage. Like weight shifting to generate power is great, but if you can shift your weight to generate power, then fajin driven by shefa is not really necessary. Fajin by itself is great, but if you have to shift weight to generate it, then it's too slow and takes too much room, which again kind of negates the purpose of short power. But separating them is hard and counter-intuitive, so without the impetus of context-specific fighting it's easy to lose sight of the purpose and drift to something easier.
Six of one, half a dozen of the other, I suppose.
