Well possibly bc of 3 reasons:
1)wasnt a headshot.
2) hit 2 people so he didnt receive the full potential damage of the attack unlike zoro who was the first to be hit.
3)law was present when kaido one shotted luffy so he had the opportunity to witness thunder bagua before, meaning he knew what was coming to him.
