Thanks, I think your first image solves the first offshoot mystery - it's actually an unmapped connection to the upper track, the western-most one.
I've mapped it now based on your image and the surface model.
If you check this against the surface model, you'll see that the western-most path is up the ridge, the middle one is along the bottom, but the path-turning-track in your sequence is sort of supposed to start to the left where there's no path visible: https://www.mapillary.com/app/?pKey=453535529915635 .

My sequences have just processed, and here's the bottom path: https://www.mapillary.com/app/?pKey=780970032970585 .

Also no path in my NE take of that track (although it was getting dark in the forest by that time): https://www.mapillary.com/app/?pKey=421715033467779 .

Also attempted to find the other end of this track, didn't spot anything. Nothing on the right side: https://www.mapillary.com/app/?pKey=776144963465364 . Nothing on the left side: https://www.mapillary.com/app/?pKey=812930863249462 .
