Other teams just end up throwing by playing among themselves, or during the macro phase they play on the opposite side of the map and force the top laner to play cleanup duty.
But BLG clearly knows that the side lane growth value of their top is better than their mid, so they run a proper 1-3-1, hold what needs to be held, and pour resources into the side lane.
Unless it's a truly important objective, they don't overextend and get caught, so they let the side laner play comfortably, and Bin delivers in teamfights based on what he's been fed.
I mean they went to Worlds finals with Bin, so what do you expect
