Right - I think "places _made_" is the key phrasing.  It seems that this 
is intended to exclude Evil-type paths, otherwise there would be no need 
for the "and is..." at all.

In particular that would seem to necessitate an asymmetric method, 
therefore it would in particular answer my original question.  Again, 
there are some silly examples such as
3478.1478.1258.1256.1456.3458 (which is true).
but I doubt whether there is anything more sensible.

I still think there should perhaps be some nice answers to my original 
question: asymmetric methods with all blue lines symmetric.
