Because you want to keep the momentum and tempo of your arms with the drive and finish of the kick
This answer should be personal to you, but here's an outline.
Think of a time where you came across a problem in your life like an argument with a parent or something, but once it was over with or soon after you got through this conflict it came out better for you and the parent. For example (this is a bad example I you shouldn't use it) If I were to fall off a cruise in the middle of an ocean but luckily I landed in some random shallows plus I found a clam with a thousand dollar pearl in it then that's a win-win situation.
