You assume that the information stored in what Unix filesystems call an
owner field is necessarily related to the ownership of an AFS file.  AFS
permissions work sufficiently differently from Unix permissions that I
would not want to make that assumption; it could well be used for some
*other* notion of owner, such as containing directory (since AFS
directories also are not quite like Unix directories), or even for
something else important enough to warrant storing in the inode but
unrelated to concepts of ownership.
