That is because the front spar of the vert stab attaches with only a single bolt/nut on the 10, unlike the others which use a grid of 4 bolts. So the flexible structure (the entire vert stab) anchored at a single point needs to be thought of as pivoting minutely around that bolt.

The vertical stab of the 10 is similar in attach method to the main wing, with the difference being the front (instead of aft) spar being the single point used to set sweep/AOA.
