You don't understand.

The previous posters are talking about _simulating_ moving sound
sources. So you, the listener, stay in place, and the composer or sound
artist is crafting cues for you that will simulate the movement of
sources around you. If those sources move towards or away from you (ie:
have a radial component of the velocity vector) then you should simulate
the doppler effect they would have if they were real objects. It is a
very powerful cue.

So, yes, it is doppler and no, use of the term is not bad or incorrect.
