Considering that Phalangitai were spaced between 1.5 to 3 feet apart, and that both their hands were holding the sarissa, is it possible for any member in the square to be pushing their mates forward? If there weren't any pushing, I doubt the phalanx could have its massive forward power only through the display of spears, especially against professional heavy infantry. So, was there any pushing done in the formation, and if so, how was it possible?
