The condition "If a player has earned a ribbon in the past 7 days but already owned it" becomes true the moment the ribbon is earned and ceases to be true 7 days later. And it definitely doesn't become "true twice" if e earns a ribbon a second time; it just extends the period of time for which it is true.
