Comment(by juh):

 Sorry, forgeit my comment. It is as I said initially, but my example was
 wrong. Should have copy past...

 g = np.array([[0,1,1,0],[1,0,0,0],[0,0,0,1],[0,1,1,0]])

 Effective "strongly connected" groups :A=[0,1], B=[2,3] with symmetrical
 The additional edges (0->2) and (3->1) make the erroneous single cluster.
