I know that is the rule, but I don't believe that is how it is played.
Here is what it says for one instance
"If the cue ball contacts an already pocketed ball, the cue ball will be considered pocketed whether it rebounds from the pocket or not."
Everyone at one point or another has had a problem following a ball you just made in to force 2 to go on the spot. The way this is written, just load up your pocket with all the balls you have and shoot the first ball (have it hang up because of all the other balls in the pocket, and then have the cueball touch that ball which is considered pocketed and neither ball went into the actual pocket to stay.
