Let try this: have 10 points on a piece of paper then try to connect each point to other nine points, i.e, point 1 to 2, 3 ... 10; point 2 to 1, 3 ... 10; point 10 to 1, 2, 3 ... The total will be 90 arrows from all point to all others
Now, select 2 points as sorting hubs, let say point 3 and 5 are the hubs, all points 1, 2 ... 10 will connect to either hub 3 or 5, then it will connect to all points, including between 2 hubs 3 and 5.
You will see the reduction in number of arrows, from 90 arrows to about 20.
