Not if he snaps the rod at the moment when the line of sight is at
right angles to the direction of motion of the rod.

I snipped the rest, because the observer knows how to make corrections
for the light transmission time, and unless he is an idiot, he does so
before making pronouncements about the length of the rod as measured
by him
