By "which place a submodule is at", do you mean the commit it points
to, or the path at which the submodule is found within the parent
repository?  Continuing on it sounds like you meant the former, but I
was unsure if you were asking mutliple different questions here.

Only if both commits also contain the base; see lines 328 to 332 of
that patch.  So, if the submodules are rewound, that algorithm would
leave them as conflicted.
