In defense of his handle angle, keep in mind we're talking about a Mach 3 which has a built-in pivot. I believe he's actually correct - the way it would disperse force across the cartridge area (in contact with the face) is more even than if you pull the cartridge forward with the handle at a 30-45 degree angle (which would put most of the force on the first blade, and the least on the last). So, with regard to angle when using a Mach 3, he's onto something. I was doing that myself when using foamless gels and my Fusion and it did help (though I still got in-growns and had to buy $15 cartridge packs).
As for the rest of the video, it's a sales pitch in an instructional's clothing. But he's not an idiot. As has already been pointed out, it looks like he removed a lot of beard with very little fuss, so his method is not totally without merit.
