The situation centers on the moment of aid during the final push for the summit, where a rescuer attempted to hand over oxygen canisters to Rob Hall and Doug Hansen at a narrow, exposed point just below the top known as the Hillary Step. The Hillary Step sits on the southeast ridge and is a well-known bottleneck right near the summit; it’s a place where climbers pause and where help can still reach them before they commit to the final, strenuous ascent. That’s why this location is the one described for delivering the canisters.

The other locations don’t fit the moment described. The South Col is a high camp well below the final ascent, not the spot where a last-minute oxygen handoff to Hall and Hansen would occur. Base Camp is far down the mountain, out of reach during a rapid upper-mountain rescue attempt. The Summit would be the goal to reach, but the delivery of oxygen to those climbers happened before or at the last stretch near the Hillary Step, not at the actual summit itself.
