I would argue the sockets make cutting the tubes easier and faster (straight cut vs miters), allow the stays to be wider apart to accommodate wider tires without bending/shaping, and as Peter notes assemble more quickly via brazing vs filet. In other words, I suspect the lug caps accommodate quicker/less error prone assembly. I don’t know that the objective is a stronger joint although that could well be a benefit of this method.
