Actually, they do. You faintly remember him saying it was a fluke getting that much draw. Dr. Dave remembers something very similar. Now, take what we do know... he obviously hit the shot with low right. So, the Z shot is totally out of the equation. (would have to use low left for the Z shot)
He obviously planned on drawing the cb back. (that, or he wanted to follow and totally screwed up and hit the wrong half of the cb. {not very likely})
Since several remember him saying it was a fluke to get that much draw, and he himself looked surprised by it, it is safe to say he wasn't trying to draw it back that far.
Given the above, wanting to draw, but not all the way back, just where is the only logical place to draw to? Yep, the left side of the table somewhere below the side pocket. He surely was attempting position for a shot on the 5, not to play a safe on himself.
