It doesn't work that way in AFS - AFS does have some implicit rights, but if you don't have a read ACL for a directory, you can't access files in it, regardless of their ownership.

I wonder how they can do something like that reliably in a cross realm
context.

Files that get written to a volume in a cell are owned by the user's ID in that cell's protection service database, not by the local UID on the machine which wrote them.
