I agree that a lot of ingenuity went into building that bench, but I'm not sure he's ended up with anything worthwhile. I suspect it's more gimmicks than practical solutions.
It's basically a lot of small capacity, economy machines that swing from underneath the bench to on top. Woodworkers tend to outgrow entry level machines pretty quickly, but in this case he's stuck with them as the bench can't easily accommodate any changes.
This lack of versatility also carries over into the layout. Let's say he's using half the bench for a glue up, but then wants to use his bandsaw. If the bandsaw was stored on a shelf elsewhere then no problem, but if the bandsaw is directly below the glue up then it scuppers any progress.
One of the key requirements of a practical bench design is ease of clamping, but this design offers very few clamping opportunities.
