That quote is referring to the 21+ day holds that paypal puts many eBay sellers through. I know this very well personally having sold a number of items on eBay, where paypal randomly decides that this auction but not that auction will have its payment held for 21 days or 3-4 days after I have confirmed delivery of the item for sale. Where sometimes they don't even release enough money for you to buy shipping for the item.
