I spent a good minute trying to work out how you could get 20 sides when theres only 4 edges per rectangle, 12 edges is not quite 20

Not my finest moment

for a minute you were one of this filthy casuals just dancing with no understanding of the geometry of planes and shapes.

Are they rotoated around the center or how are they positioned?

Mutually orthogonal is a mathy way of saying at right angles to each other. No rotation, think of putting the rectangles on the 3 planes of a 3-axed coordinate system.
