I'm not quite clear what you're asking, but you can set your affiliate hoplinks to any landing page URL you choose -- it doesn't have to be a product page, and the buyer does not need to purchase your product immediately after clicking the affiliate link in order to earn a commission for that affiliate.
When a buyer clicks an affiliate's hoplink, that sets a cookie in their browser which expires in 6 months, so any affiliate-eligible product that buyer purchases from you during the lifetime of that cookie will earn commission for the referring affiliate. After the topic you linked was written, we have also added support for a common hoplink and percentage, so it's no longer necessary to set a landing page and percentage for every individual product.
