This is correct if you are constantly changing gearing and using a rear brake. I do change gearing on my FG, but do not use a rear brake. My SS has a rear brake, but I don't change gearing. I think this might become an issue if you had a flip/flop fixed/free with different cog sizes, and had to constantly re-adjust the rear brake. Of course, this is the reason why horizontal dropouts are not truly horizontal, but slanted such that the distance from the rear wheel rim to the brake bridge doesn't change as the wheel is moved in the dropout.
