I have only seen the pictures you just pointed out - but it looks like they are using customized asymmetric lacing techniques to warp a generic boot to fit individual feet.
Note how the boot they show is kind of boxy - not really fit to a particular human foot. So it needs a little help to fit.
That's not to say that the lacing ideas are at all bad: you do want to make boots fit as well as possible. I'm all for experimentation. But maybe it would be even better to make the boot fit the individual 3D shape of the particular skater's foot to begin with - at least for customs.
Just an opinion, not backed by experience with these particular boots or with those lacing ideas.
The one they show first, with only laces straight across, looks fairly unique, and it took me a while to figure out how they did it. I don't know if you can tie that very tight, but it's still cool.
