Yes, it will make it active, but that doesn't matter here, because at this
point (in create_lib_submodule_repo) we prepare an upstream
in submodule_update_repo

Any later test follows the structure of

    prolog &&
    reset_work_tree_to no_submodule &&
    (
        cd submodule_update &&
        # do actual test here, in submodule_update
    )

Note that 'prolog' performs a clone of submodule_update_repo
to submodule_update, manually setting 'sub1' to active.

'uninitialized_sub' is not active.

I tried to explain it via
    To test for uninitialized submodules, introduce another submodule,
    that is uninitialized in the actual tests.
in the commit message, but that is too concise apparently.
So the resend will explain that a bit more.

Thanks,
Stefan
