Whether the driver was choosing a higher gear, a lower gear, or some of each vs. what the D mode would have chosen - I don't know.
Anecdotally, I would agree with this. The automatic mode tends to be more aggressive with the downshifts, even in the lowest settings, than a driver would be while cruising.
