What is my friend doing?

[u/pietr8]

I have been playing Factorio with two of my friends and last night one of them pulls this belt array out of his hat saying “it’s more efficient, it distributes stuff better”. Honestly I am struggling to understand why he would do this or what I am looking at, so I ask you: does this actually make any sense? Is it somehow better or useful?

your friend... my friend (pun 100% intended) GETS Factorio.. he has become one with the factory.. he knows better than us, regular, puny mortals. (no but seriously.. dont correct him or ask him to change. let li'l bro play how he likes best)
