If engine speed stays the same and load goes up with no change in mileage then engine efficiency must have gone up. If there's a steep enough downhill grade it may be worthwhile, depending on fuel trim during acceleration, to give it a little gas/pop into neutral/rinse and repeat since there still is some difference between load and efficiency on a TDI, it's just not as large as on most gassers.
