After some verifications, it seems that the text that's written in the documentation is more or less verbatim from paypal's own marketing material (albeit, probably some older one).
I'll be correcting this page as I'm in charge of documentation.
Roffe, you'll have to contact Paypal for more information on how these services work. Because we are only a "link" to PayPal, it uses their own system for payment, and we have little to do with how it works. Whatever option they offer, it's not something that can be configured or setup on our side.
The service you're looking for is probably
PayPal Payments Standard, and there's contact information on that page to get started with the service.
