Yup.  

When GIT_DIR environment variable appears without GIT_WORKING_TREE,
"git" assumes that you are starting it at the root level of the
working tree.  In your example, if there is README at the top-level
but dir/README is not there, "status" would report that you removed
it.  You can unset GIT_DIR in your --exec script if you know that
Git would find the right repository when run from your script.
