The relevant citation for shots going over a unit not conferring cover saves being page 22:
Firing through units or area terrain: If a model fires through the gaps between some elements of area terrain (such as between two trees in a wood) or through the gaps between models in an intervening unit, the target is in cover, even if it is completely visible to the firer. Note that this does not apply if the shots go over the area terrain or unit rather than through it. (emphasis added)
