It looks like he's just explaining what happens when the box rotates and the plane gets compressed/foreshortened because of how it lines up with our vision.
>isn't this about a single plane
Its about both planes as in your example the green angle plane, or the farther facing plane, is proportionally wider then the closer blue angle plane. And foreshortening works both ways so as the plane on the left side gets "compressed" the plane on the right gets uncompressed/wider.
Please excuse my awful boxes, i feel they only do a mediocre job conveying the concept so i'd suggest looking up a see-through 3d cube model to mess around with so you can get a better understanding of it in action.
