This is a very peculiar definition of "mirrored" edges. Value are reflected at the top but not the two sides and the bottom.

Not just peculiar but non-uniform as well. Feels more like a pattern the Author made to his liking

That's a bizarre mirror. And as others have pointed out, it seems the first rows are incorrect since they behave differently from the left, right, and bottom mirrors.
