No Trespassing in This Area

To be honest, although Aoto knew Yhwach had a substitute, once the fight truly began, he forgot all about it.

The Yhwach before Aoto was genuinely terrifyingly powerful.

Even though Aoto had nearly fully unleashed Garaku Kairo's power, reaching the level of Bankai, he had still been suppressed the entire time.

Power on this level truly made Aoto believe that this was the real body.

Only when images of his subordinates being slaughtered flashed into his eyes did Aoto finally snap out of his total focus on the battle... The Yhwach before him was a fake.
