A frame perfect standing 2 after a standing 2xxNDC eventually whiffs on everyone except Kenshi. And Kabal's standing 2 is a S.Mid anyway, it won't hit you in an offensive crouching state. It's good for making your opponent respect your option to follow up with a hit-confirmable launcher, but relying on it as a true block infinite is more trouble than what it's worth.
Ultimately Coolwhip's point was, the NDC comparison isn't relevant to this. WonderChef had it right with the Cyrax comparison.
