Yeah, it can be confusing.
As long as you OWN a premium site, you automatically get the points. When you transfer ownership to your CLIENT, you lose the points. However, you can reclaim those points if (1) you are still a CONTRIBUTOR to the site and (2) you SUBMIT the site on the Partner Dashboard.
By the way, it can take a little while to get the submission approved.
