I would have to go back and look at that video, been a long time. It sounds like a shear scrape which is what you call the cut if the tool is at an angle to the spin as opposed to a scrape which has the cutting edge at 90 degrees to the spin, or flat on the tool rest with standard scrapers. By rolling it up onto its edge, you can get a rounder shape into a tighter space since it is skewed rather than square to the form. What and how you do it depends on the shape of the box form and bottom. So, if the bottom to wall transition is almost square, pretty hard to do. If the bottom is more open and round, then a properly shaped nose is easier to get through the transition, you just swing right on through. If there is a small radius transition, then when you get to the corner, that would be when you need to get the scraper up on edge. With an 'inside' scraper, which is swept back to the left side, I would want the nose rounded back a tiny bit to the right, like 1/16 to 1/8 inch radius. This makes it easy to go through smaller spaces, and if you roll the tool up on the edge, and handle is level or slightly down, you can't get high sided (high side, farthest away from contact point on tool rest catches, kind of like the skew chisel spiral dig in). With a more round nose, like Doug Thompson's fluteless gouge, you can pretty easily roll it up on edge, and keep cutting with the lower half of the tool. I actually prefer negative rake scrapers for this now as they are 'catch proof', but I can probably figure a way to get them to catch.....
