I think Gunsmith's anti dp+K video was a bit more useful than this one. This video seems to show only the dp+B rather than dp+D which has a more lower flip in the air. Plus, honestly, I wouldn't condone blocking the dive kick, I'd rather roll during the flip, standing jab (or any normal that hits above your character's head or a normal that has a horizontal hitbox at shoulder height), or jump backward on reaction to hit Yuri, and to give yourself some space.
