I'm not exactly sure what you mean...helper edges maintain a sharp edge for use with subdivision surface smoothing (subsurf). Extruding and scaling doesn't serve the same purpose. Though I may be misunderstanding the question.
I'm sorry that my question was a bit unclear, I meant the edge loop you extruded at around 1:09 and deleted afterwards. What makes it a better method that just extruding and scaling to the 3d cursor in the middle (of the entire object, so exactly in the middle of the mirrored object)?
Oh oh, my bad. I did use the term "helper edge" in the video but incorrectly translated that to "holding edge" - 2 very different things. I'm the causer of confusion here!
So in that specific case, the oblong nature of the shape means scaling would not produce an even bevel; the top/bottom edges of the bevel would be a shorter distance than the side edges. Using ALT + S to push the helper edge according to the normal is what gave me an even bevel.
Though in hindsight, the technique in the video is not the optimal option. I could have filed the face, extruded slightly and then used the bevel operator to get an even bevel. That would have likely been optimal.
