User Agreement Update

[mostly-everything]

I just received an email about the updated user agreement.  One thing concerns me from the email:

• "We may automatically renew your fixed-price listings unless your listing sells out or you cancel your listing."

What does this mean?  Ebay is going to relist any of my listings that do not sell and I may not want to relist??  I know it says that I may cancel them but I just let them go to UNSOLD and decide later.  This sounds like if they don't sell, they will put them on again.  What, this is out of my hands now?  I may not want an item to relist and don't want to spend any more money on it unless I catch it and cancel it?
