A dieting program is a procedure for training and a procedure for being thin. Neither function is independent of the other.

Yes, but interdependence in purpose is not the same as causality. 

And one is a nested relative clause and one is a nested purpose clause. I'd only expect to see causality in a purpose clause.

While one can perhaps tease out some minute difference in meaning here, I don't think it's something the average person would be parsing — unless Okrand were to arbitrarily tell us that it is.
