That is only true when receiving the signal via direct line of sight
propagation.
Once the signal is over the horizon, and is using the ionosphere to
propagate the signal, the reflected signal can and does come back down
at any polarization.
Matter of fact in minutes it can "Rotate" from vertical to horizontal
and anywhere in between. or even faster rotation. QSB is mostly caused
by this polarity rotation of the signal.
