Well I might be reading something that has been lost in the translation but I would never put an ETP on the LEGS so as to cause the FMC to look at that LAT/LONG as an active waypoint. Bad procedure and if you are using ADS-C I would expect a call from the controller asking where you might be going? If that waypoint was not a part of your ICAO flight plan, then it should not find it's way onto the LEGS page.
