No.  Tagging is never used to deduce changesets. Look:

/*
 * The heart of the merge operation; detect when two
 * commits are "the same"
 */
static bool
rev_commit_match (rev_commit *a, rev_commit *b)
{
    /*
     * Versions of GNU CVS after 1.12 (2004) place a commitid in
     * each commit to track patch sets. Use it if present
     */
    if (a->commitid && b->commitid)
	return a->commitid == b->commitid;
    if (a->commitid || b->commitid)
	return false;
    if (!commit_time_close (a->date, b->date))
	return false;
    if (a->log != b->log)
	return false;
    if (a->author != b->author)
	return false;
    return true;
}

Because tagging is never used to deduce changesets, the case does not arise.

I have added an item to my to-do: document what the tool does with
inconsistent tags.
