What the hell is the overlooking view? (LNs)

Both Mikiya and Touko talk about it from a very literal sense as to give the idea that it either means superiority or the curiosity in death and falling. When you are stood at your normal height you are overlooking the part of the world you can overlook but when you stand on a height like a building you can overlook much more and see how much further away you are from the ground and surroundings.

Maybe the higher you climb the more disconnected you become and you become more infatuated with your darkest thoughts even if only for a brief moment.

With that said, I dont see how the hell this ties into our antagonist at all other than the fact that she likes to dance around atop a building. Maybe i missed something?
