Ogres have different animation when object is thrown into them so they can't be pushed through the invisible staircase wall. But Narhari Kahn can. Pair the ogres for DTD and then have your way with Khan and the locker boy at your  leisure.

Someone updated the Guide to reflect   that  in the meantime but I remember it not being specific before so I'm not surprised about the confusion.

On a personal note, this is one of the more tedious DTD pairings in the game. Always hated it. To make matters worse some soldiers may spawn in Alice Garden Pods walls in the shamefully buggy Director's Cut version of the game...
