It sure is surprising, and not super intuitive.

If that’s what your are trying to do, ‘git submodule foreach’ [1] seems like a better way to go.
For example I have an alias ‘st-sub’ that calls git status in the superproject and then recursively in the submodules:
$ cat ~/.gitconfig | grep st-sub
st-sub = !git status "$@" && git sub foreach --recursive git status "$@"
