Guess they want to make Kaido look better by extending everything but the sequence of events being so quick in the manga made you understand Kaido's anger at the old lady's intervention. You could tell everything happened too quick for him to stop his final attack so the impact it left on Kaido (that he won due to a handicap) was pretty great. If Kaido is going toe to toe with Oden after the scar, he looks better than in the manga where he got cut, was about to be harmed further then got the drop on Oden due to unwanted interference. We'll see how it goes, I guess.
