The Nacra manual shows the traveller track running the full length of the rear beam. Mine has a stain in the beam where it looks like one used to run full length, but now finishes short, on the inside of each hull. The plot thickens.
Nacra made two versions of the legacy rear beams. The earlier version used a bolt-on traveler track that ended short (inside of each hull). The newer rear beam included the traveler as part of the extrusion, so naturally it would be the full length. There was a slot machined into the track to allow the beam straps to pass through. Sounds like you have the earlier version.
