i thought d-barrier just extends the time the damage barrier is active?

im taking into account the structure of the X series engine to try to argue that just clouds first touch on x will not activate damage barrier
and i still dont really see though how that proves that a throw attack version of omnislash would be affected by the invincibility
cloud is effectively going up and executing a throw attack on him.. just because he does not get stunned would not prevent him from being hit
it might allow X to instantly make a counter attack.. i guess
