Honestly, I suspected this youtuber for using fastbreak. I am not sure.
Why?

Idk if the yellow wool was broken by some other issues, however breaking a block(bed) while jumping is more slower. There is even a person blocking him. This is just my opinion. (I think that the lag issue but he still hit through the player)
I slowed down it into 0.25 slow mode and I found out that he tries to break the bed and got hit away. He also stopped breaking the bed for awhile, but how is the bed gone?
I also sees that he is still holding down left click, attempting to break the bed. But the player is infront of him. Which means he hit through the player.
I am waiting for someone to answer my curiosity about this case.
