I should have been more clear - using ADL, the camera MAY (rather than WILL) reduce the exposure. Whether it does or does not depends on the distribution of light and shade in the image as metered. If the scene is mostly mid-tones, with no significant areas that are in danger of being "blown out", ADL would not need to apply any exposure reduction.
Since your test shots all had the same exposure, I would expect to see no visible difference between the three NEF's when opened in Aperture.
ADL is a pretty "intelligent" feature - it can be a challenge to understand how it works
