It's actually not contradicting itself. Rotation games are a matter of patterns. Repeatable patterns. What makes the draw shot "wrong" is that by taking that choice when there are better choices to make, you are setting up a pattern in your mind.
Then, down the road, when something similar comes up, you will tend to shoot the shot the same way. That is where the "wrongness" comes in. Yes, you may be successful going that way, but you also have a lower percentage of getting out that way than by going several rails around for the eight. More can go wrong with the draw, and eventually it will go wrong more times than the other way.
You want to set in your mind the "correct" patterns, meaning, those patterns that have the least chance of something going wrong.
