Perhaps with good reason, some are wary of "canned" methods, because some photos are unique and (especially with Large Format) we usually prefer that they not look contrived after sharpening - as ic-racer has described so concisely.

The stated goal of the technique outlined in the video, is to sharpen selected parts of the tonal range - in order to avoid sharpening artifacts - but it's a rather circuitous approach.

You might like this simpler and faster method which also gives greater control: Sharpening the Dark and Light Layers Separately.

With respect to the Zone System, we might call it "Zone Sharpening" because we can sharpen any section of the tonal range to taste - separately - or not at all.

It's not a complete approach either: we often need to sharpen selected regions of the image (and ignore or even blur other areas), as Peter has explained. As with everything else in Photoshop, there are many ways to get there.
