What kind of sorcery is this

I added "5" to pic 2&3 as a reference. Those green vertical lines has the same height. This is asuming the camera is not moving 😄

Area... The square cardboard frame they use at the beginning is not the same they use at the end.

Old trick thst works because of the space between the parts is used to tighten and get more space.

He replaces the external square with a bigger one to fit the new system....

Sorry.. impossible.

He is using margin on four sides. In the beginning you can see a visible gap on every side but when you see last there is no gap.

illusion made by lack of sharpness and increasing width's frame

Frame's getting bigger 😮‍💨

It’s just tighter packed at the end via moving some pieces and filling the extra space with a new shape…
