The Templar paragraph is there because it is a concrete, documented instance of the mages reaching out to the Templars. The mages are allowing the Inquisition to hold them accountable to do what they say they will do, and the ball is now in the court of the Templars. Moreover, this document isn't just for mages, it's for the non-mages of Skyhold to see what is being done about the recent possession.
