The next blast Thanos blocks. So it's not like he didn't know it was coming. I don't get why this means he can react to Superman. Maybe Josh is thinking of another feat.
Even if you know a bullet is coming your way, you'll still be hit.
Besides, he still had to move his hands pretty fast to block all 6 beams.
