I'm not 100% sure, however, I think that the double dot (..) shows the connection between a SID (Departure Route) to the enroute portion of the flight. Also, later in the flight, it shows transition from enroute to the arrival routing, however, this particular flight plan does not have a STAR (arrival route). So the double dots just show the separation from enroute to destination. Other than these times, one dot separates all of the other fixes.
