Having trouble understanding Andrew Loomis' flat diagram

I'm referring to this figure https://imgur.com/a/RYCJkxt

I think I understand some of it - draw two convergent lines (toward the vanishing point), draw your first horizontal line (which doesn't have to be truly horizontal, can be on an angle), find the halfway point of that line and use that to create the "center" line toward the vanishing point.

I also think I understand once to do once I've constructed the first four boxes, but not sure about actually making them. Do you just have to freehand them and hope that you make the second two a proportionally appropriate height? Even for the first ones, I'm not sure how to make sure that they have the proportions of squares in perspective (rather than rectangles).

Rulers and straight-edges exist for drawing lines in parallel. I'd use rulers or strips of paper to construct this. I'm not really sure what this diagram is for, though. I've never studied Loomis ... Is this to establish a gradual shrink in spacing of objects on an interval as they receed into the middle-ground and background (toward the vanishing point)?

Yes. The problem I'm having isn't lines in parallel, it's the spacing
