Yes it is. Magnification over 1x made the 3d waves dissapear and the horizon blurr. OLC did not want that, and thus fixed the zoom at 1x and instead worked with the field of view to set the appearence of the image as if zoomed at the required power. IIRC he had to go for a compromise, with the obserbation scope having bigger zoom than the attack. First one allows locating and identifying target at long range, then when close enough you start using the attack one.
