Assume we have DAGs, NOTs, DAGs, NOTs, and then DAGs.  Let X, Y, and Z be
the DAG groups such that the leading DAGs are x, y, and z.  y won't match
overlaps with matches from:

1. X.  Otherwise, we used to get a spurious reordering complaint (back
   when reordering complaints on DAG-NOT-DAG were still implemented).
2. Y, because y is in Y.  To prevent these overlaps, the implementation must be
   careful not to drop y's match from the previous matches list when it drops
   matches from X to save search time.
3. z.  This follows by applying rule #1 for z instead of y.
