I understand the --git-dir=$HOME/x.git to keep track of
something in $HOME/foo/bar example.

But that is not the issue you described in the original message.
I was asking about this (which is the way I read your original
message):

    $ GIT_DIR=$HOME/x.git git init
    $ mkdir $HOME/x.git/workroot
    $ cd $HOME/x.git/workroot
    $ git --git-dir=../ --work-tree=. 

That is, $HOME/x.git/ is the GIT_DIR that has HEAD, index and
refs/, and you are keeping track of contents whose rootlevel is
at $HOME/x.git/workroot
