@DeadStick I figured out Alex's shot. His video is actually TWO attempts. On the first attempt, at the very beginning where he is screaming, he hits it one rail like you and me were. Then he talks about the shot, then shows the shot a second time from a diffenrt camera angle. This second shot is the double kiss, the CB never hits the long rail at all.
Since you are on a mac, download the video with the link you sent, and open it in VLC. Press the e key to go frame by frame, and you will see the first shot is 1 rail thin, the second shot is a double kiss.
Downloaded and analyzed the second video. The second shot, showing the whole table, was a thin cut as well. May have been the same shot as the first video, just from a different angle.
The CB hit the long rail just to the right of the OB, but you don't see it when looking frame by frame, because it happened so fast it's missing from the footage (there's a 4-6" gap between CB positions in each frame).
Look again at frames 1 through 5 below:
Frame 1 clearly shows the CB approaching the OB on a thin cut line at high speed.
Frame 2 shows the CB headed across the table to the opposite long rail, at a high rate of speed. The rebound off the first long rail just to the right of the OB happened just before this frame. The blur of the CB shows its path.
Frames 3, 4, and 5 show the continuing straight line path of the CB.
At the bottom of these five frames, I show a composite overlay with more notes...

The path of the CB in shown in red. No way it did anything between frames 1 and 2 other than rebound off the rail. You can also see 5 images of the OB, showing it's taking a straight-line path to the pocket, as the thin one-rail cut bank would send it.
If it
had been a double hit, and the CB had not hit the rail, then the CB's line of travel would have started from where the OB was originally, not 2 inches or so to its right, and the OB would have shown more deviation from its straight-line path.
