Complex question, you have not reversed the way it is hooked up, (I can see that making a difference due to opposite phase currents through the chassis and subsequent stage), you just possibly wound in reverse. It would be a study of the magnetic coupling fields built up on each winding - one way vs. the other, and also how the shielding cans affect it. Probably won't notice much in the 70, but never know, winding in opposite might affect the quality of the transformer.
