No, since that will be two distinct edges, a B->A edge and a C->A edge.  But
suppose A has FriendOfAFriend set, but B and C do not, and B and C are also
connected to each other. Then it is possible that the B->C edge information
(that B sends to A and C  at some point) gets anonymised by A and forwarded to
C, which sees new information, and forwards it in turn to B, which will see
that someone forwarded the B->C edge, but with wrong IP address information.
