[SI-LIST] Even and odd mode xtalk for three lines

Hi all SI gurus,
 
Question,
which one  is the correct definition for even and odd mode crosstalk simulation 
for a three line system --aggressor1, victim, aggressor2?
 
case:
 (1). Aggressor1 , 2 are  in phase, victim being high or low state           
 (2), Aggressor1,  2 are  in  opposite phase, victim being high or low state
 (3), Aggressor 1, 2 are in phase, victim is in opposite phase at transition 
state
 (4),  Aggreesor 1, 2  are in phase, victim is in phase at transition state.
 
 For (1) and (2), the phase between two aggressors is to define even or odd.
 For (3) and (4) , the phase between aggressor and victim is used to define 
even or odd.
 
Shall the phase between aggressor and victim define even and odd mode?
if yes, then (3) shall be the correct definition for odd mode crosstalk. 
 
Will the amount of crosstalk for (1) and (3) be the same because of 
superposition?
 
Thank you for your guiding in advance,
John
