I didn't see if you posted a link to the video...
However, I was shooting in a tournament years ago. The tables had drop pockets (not the webbed style..the plastic cup style...can't think of a better way to explain it). Anyway, the bottom of the pockets were kind of "springy". I hit a shot into a corner pocket kind of hard (needed full length draw). The ball went in the pocket, hit the bottom and bounced back onto the table and sat in the jaws of the pocket. Didn't count as a "made" shot and I lost turn at table.
