I could easily see a general deliberatly charging some cavalry at a point in order to disrupt that point, so he could force his men through that gap and attack the phalanxes from behind. A cavalry charge is much more likely to carve a gap in a phalanx line than an infantry charge, if for nothing else than a wall of spears impaled on horses can't really do much damage to subsequent attackers, where a foot-soldier attack could be held off for quite a while by a spear wall.
