I wish I could edit my posts!
So, in my example, it looks like the sales on the main site showed up after all (it took some time): users are bound to affiliate, not by domain.
To be sure, I would like to test the scenario where you register under an affiliate (AF1) on the main site, then go to someone else (AF2) WL to see who gets the sale. According to our belief, AF1 is the winner. Someone wanna try this?
