The reason why I interpret this way is that pikeman is a special infantry army organized when cavalry is absolutely numerically inferior. It is confirmed by Han, Tang and Sung of China, and Rome in the West, and it is also seen in infantry armies of England, Scotland, Flanders and Switzerland J. F. Verburggen, renowned Belgian historian of warfare, stated that pike was a basic weapon for infantry to use in battles against cavalry. He stated that pike was long and heavy and its point was thick, which was appropriate for planting its end in the ground, When heavy horses rushed toward infantry soldiers, pikes, unless being planted in the ground, would have been pushed out by the rushing forces of horses, which would have fatally injured infantry soldiers. Consequently, two soldiers were required to hold one pike, with one planting its end in the ground and the other holding it at a certain angle. Pike infantry arrangement was taken at the confluence of rivers and against the rivers, or crown-shaped circular formation was taken in the plains without any obstacles. It was to avoid attacks from the flank and the back. Pikes aimed at horses' hearts or necks, not soldiers on the horses. In other words, the main purpose of pikes was to drop soldiers off the leading horses and stop the movement of the whole cavalry anny. The stopped cavalry army was nothing but a disable thing without mobility. The cavalry anny would be so congested like a traffic jam that they could not use weapons at their disposals, and consequently, they would be fatal when attacked by pike infantry.
