First of all, most people don't see that button and close the window so they never get the after-purchase instructions. Second, that page with the after-purchase instructions looks almost like an error. On that page, in the top left hand corner it says to fill out the form and wait for an agent. I think that you should be redirected to the form automatically after a PayPal purchase or any purchase. Then, I wouldn't have to wait 3 days for the Middleman transaction to be set up, all whilst assuming the buyer had completed that form!
