Dashing into Down-Tilt

[AirFair]

Hello.
So I was watching the match between Ken and Scar at KoC4
http://www.youtube.com/watch?v=FtcIyLYohg8&t=9m17s
in the video, Ken does a dash dance, and then right as he ends it, he does a down tilt, which left me confused
Whenever I cancel the dash into a down tilt, I usually have to dash a bit farther than he did to cancel it.

Is it that I have to input the crouch right as I start dashing? Do you guys know?

He just did the crouch ditilted like right after the dash ended. You just have to be on point.
