My daughter played varsity volleyball and travel volleyball for years. You would oftentimes play teams that you knew a few members on the opposing teams. You visited with the players and their parents. My grandson runs varsitybbm

Why would a student, or anyone for that matter, sit in the other school's area? Even if it was a mistake, wouldn't the student realize it and move? (Maybe not, but I doubt it.)
We had a "home" side and a "visitors" side, so it was easy to see the difference WRT the students.
Maybe he sat there on purpose, for whatever reason? Anyway, he is in Big Trouble now.
And a family has lost their son.
Cross Country and the runners do visit with members of the opposing teams. I don't find that strange.
