Antenna gain question

Such a claim might be remotely plausible were it not for the fact that
rotating a directional antenna does not "coherently sum all the rays".
Seems to me, a receiving Yagi causes constructive interference
in the forward direction and destructive interference in the
rearward direction.
But does it seem the antenna causes destructive interference when the
forward direction of the radiation is toward the rearward direction of
the antenna, or does it seem like it causes constructive interference
when the forward direction of the radiation is away from the rearward
direction of the antenna....and if so, what does that have to do with
"coherently summing all the rays by rotating the antenna"? Just wondering.
