I hope you're not really confused about whether he was playing it in the pocket where it went. Actually, it was a bad kick since he was probably trying to hit the ball full. The other corner pocket was nearly directly in line.
I don't know if I would call that a "nice kick" since he almost missed the hit. Amazing how it went in from that cut angle, I wold not shoot for that pocket at that angle straight on LOL
It was a great result, but for sure he has hit many better kicks with better aim.
He appeared to put the tip where he intended to hit the ball which wasn't where he hit it so I'm guessing he got "lucky". Next shot he went one rail to kick the 6 out of the way to open up the 4 - that wasn't lucky. Next shot he billiarded the 9 - that wasn't lucky.
