The point here is that D lenses can also be AF-I or AF-S lenses, with internal motors.

I don't know anything about AF-I, but my strong guess is that all AF-S lenses have distance encoders, so that they are in principle "D lenses". Most likely at some point the D designation was not any longer important for marketing because all lenses had it by default.

That's right. All G lenses include the D functionality, but they are no longer called that (G lenses are D-type lenses that lack an aperture ring).
