The measure of distortion is taken as an departure from perfect linearity with respect to the frame size. So the percentage distortion actually goes down because you're cutting off the outer edges of the image circle.

if the frame size is smaller, the percentage should go up, not down.

check out the reviews for the lens in question:

DX: -2.29%

FX: -2.26%

probably not statistically significant, right? personally, using the manual version of this lens, i found the distortion easier to live with on FX than on DX. but that's just my subjective assessment.
