(A) you need to set expect there as well, to have sub{2,4,5} be expected
there as well.

(B) That may hint at another (UX) bug.

The test case there uses "git submodule update --init".
The init flag will set all submodules to active.

Maybe you want

    git config submodule.active ":(exclude)sub0"
    git config --add submodule.active ":(exclude)sub2"
    git config --add submodule.active "."
    # Read: anything except sub0 and sub2 are interesting

    git submodule update
    # no init flag, needed even for new submodules IIUC
