Not quite, but so close it tipped me off to the real solution.

At the beginning, the borders between the pieces is very prominent. When they're rotated, those thick border edges are now on the outside, "filling in" the background border. Note when rotated, there is no highlighted border on the edges.

Basically if you think of the small squared space at the start as a 5mm x 5mm square, and the large square st the end as a 100mm x 100mm suare, then that small square would 'spread out' along the outher edge and cause a difference of about a quarter of a millimetre. The addition of a black edge along the outer edges of the final square is negligible
