I built all of my T and S-type neck with the 2-way rod upside-down. Not a single guitar has ever come back with a broken neck or even a complaint from the buyer because the rod had to be adjusted "the wrong way." I never had to force a rod to straighten a bow or even go too far off slack to get the job done. So, to me, the issue of right or wrong is moot. Just put it in the user manual which way the adjustment goes; that's all it takes.
