Yes, it's from single theme. I'm currently at the highest rate of 70%.
There are a couple of high-selling authors on TF that established their theme clubs. They build up customer base using TF and then invite people to subscribe for a yearly fee to get access to all of their themes plus the ones to be released. I guess after you reach certain amount of customers such model is much more profitable.
