Sorry, this is not the issue described above.  The code is question is
not related to the backend, but to the vc _state_.

Incidentally, the code in vc-next-action that verifies the fileset:
    ;; Verify that the fileset is homogeneous
    [snip]
might fit better in vc-deduce-fileset (or whatever is called now).
