We use one-handed spears overhand as well a lot. It is very effective in close quarters. Any doubter is invited to come to an Ask training session where I am in charge.
The pushing I find very unconvincing though as it would be suicide to get in close and push physically on an opponent changing to overhand grip and stabbing down into your neck and chest cavity.
Instead consider that when we Viking Reenactors push we take one step forwards or half a step, and the opponent- if he does not kill us as we step, will try and keep their distance. Stepping forwards is very difficult though as an underarm/underhand cross-strike from the side can easily slip in behind the shield. So often the fighting will be at weapon range while we try to thin his formation out and/or push him back and break the lines so we can roll his formation up from the side and rear.
