That is how he could get around it. And I don't see Susanoo coming close to breaking it. Madara has not shown strength enough to warp space/time so until then he can't defend against it. Even Kurohitsugi aside, Aizen's defenses are actually better. Madara has Susanoo, Aizen has regeneration/smaller barriers/immortality/above hierro-like durability.
You are referring to Monster Aizen right?
