No mate, I think it works something like this.
He puts all teams into a random generator. Say for example. Liverpool came out first, villa 2nd, spurs 3rd.
In their lists they had the same players in order like 1. Messi, 2. Ronaldinho, 3 ter stegen.
liverpool will get messi, villa will get ronaldinho because their first choice messi has already been taken and spurs will get yet stegen because their 1st and 2nd choice has been taken. If Leicester came out 4th and their 1st choice was ronaldo they would get ronaldo due to the fact no one has got him.
(I think that is what the rules works like?)
