That is, based on the information that have been available when the Priority was set, it should have not been high. It should never be high anyway, this is just a Warning (it's a W, a W, a W) after all. With the further information about the /var thing, it should maybe be medium.
But I don't see why this happens. What's the permission for the deb in question?
Side note: If you download stuff as a user, APT cannot drop permissions at all (because that requires root), so it won't show a warning and just run as a user. If you run it as root, it tries to play extra safe, but falls back to the APT 1.0 state of running the fetching code as root if that fails.
