there is no such thing as a "simultaneous rail and ball hit". this is because ball to ball contact is probably 100 times shorter than ball to rail contact.
so, it could be one of those:
1 -cue ball hits ball, then rail
2 -cue ball hits ball, and then while still in contact with the ball, hits the rail, then the other ball goes away while the cue ball is still in contact with the rail (not very likely, this one)
3 -cue ball hits rail, then, while in contact with the rail, hits the ball, green ball goes away, while the cue ball is still in the contact with the rail
4 -cue ball hits the rail, while in the contact with the rail, hits the ball, then, while two balls are touching, cue ball releases from the rail, then finally, balls separate
5 - cue ball hits rail, then ball
2 and 4 are not very likely, however they are still possible.
in the manalo's case, it is probably line 3, although it could be 1 or 2. i guess "3" is a foul, but technically, the cue ball was in contact with the rail after contacting the object ball.
