I just had a look in the Hero's Path and it's showing me some kind of teleport jump I seem to have performed:
It looks as if I teleported to a place I've never been before, which is not near a Shrine, Beast, or whatever teleportation target. I walked a few meters and then teleported away. You can clearly see that I never walked there, so I couldn't have placed the Travel Medallion there. You can find a recording here.
How did I perform this jump?
You have to go to your Adventure Log (the screen left of your inventory) and scroll over to the Memories page. There you'll be able to revisit any restored memories.
Once you get the Paraglider (or perhaps before, I don't know much about glitches or speedrunning tricks), you can head straight to Hyrule Castle, either through the front door or from the back. There will be Guardians in your way and you might get blown up a lot, but it is possible to walk straight up to the castle from the Great Plateau without doing anything in between.
To start the battle with Calamity Ganon, you must make your way into the castle proper. You'll find an area named "Sanctum" and once you step in, you'll begin the battle with Calamity Ganon.
Best Answer
After testing a bit on a save where I didn't face Ganon yet, I can say:
Probably?
Looking through my Hero's Path, I came across a few similar disconnected teleports at the locations of the Divine Beast battles, the two below being particularly good examples.
However, the final battle didn't seem to do the same thing for me. I saved some screenshots of the exact area you had in your jump before and after the battle, and I don't go in that area at all according to the Hero's Path.
I also took a screenshot of the location the battle started, and it does line up with what's shown in your recording.
It's not quite the conclusive answer I wish this was, but perhaps in previous versions of the game, the final battle would be shown in the Hero's Path, or maybe it's a bit of a bug?
Either way, evidence shows that it was most likely caused by Hero's Path tracking you during Hyrule's hour of need.
