In Emacs 23, it's not what I see in Dired for the other files and directories,
besides `..'. In my case, I see my user name as the owner for each entry except
`..', and I see `None' as the group for each entry except `..'.
In Emacs 22, I see my user name as the owner for each entry (including `..') and
`root' as the group for each entry (including `..'). In Emacs 20, I see my user
name as the owner for each entry (including `..') and `5' as the group for each
entry (including `..').
IOW, before Emacs 23, (1) `..' was not treated differently from other entries
and (2) the group was not `None'. Change #2 seems OK to me, but I don't
understand #1: Why should `..' be different?
And why should following the link `..' show something different from what was
shown for `..' in the subdir? The properties of a given directory should always
appear the same, regardless of where you are viewing them.

My hard disk is formatted FAT32, not NTFS.

No. It was and is still FAT32.

Whatever is used should be consistent: (1) `..' shouldn't be special, and (2)
`..' should show the same properties (owner group) as what is shown for it when
you follow the `..' link - the directory's properties should not change
depending on where you are looking at them.
