You've switched to counter-clockwise replication, but I think that's 
generally more intuitive anyway.  I also think of syncing as directional 
and pulled, not pushed.  So I think I'd state it (equivalently) as:

C syncs C-D from A, C-E from B, D-F from D, and E-F from F.

In other words, from each host it overlaps it syncs the overlapping 
range.  Numbers might be simpler:

X has X to X+1 and syncs:
   X   to X+1 from X-2
   X   to X+2 from X-1
   X+1 to X+3 from X+1
   X+2 to X+3 from X+2

Does that sound right?
