I was reading a thread over at twcenter.net that was discussing this issue. One possible reason there might be phalanx-capable units without the mount effects is that the mount effects are applied regardless of whether the units are using primary or secondary weapons, whereas the "spear" attribute is weapon-specific and can be applied to one and not the other. In some cases with phalanx-forming units, the secondary weapon is a normal sword or something similar, which should not have a bonus against mounted units, so giving them the mount effects wouldn't make sense in cases where they attack with their secondary weapon.

Nonetheless, there doesn't seem to be any real consistency, hopefully some of this will be better implemented in the patch, or a modder will clean this up once the true effects of the spear attribute are better understood.
