Stereo Track, Aux and Patch Point Question

[Tez]

If I have a stereo track, either an audio or VSTi associated, and set the output to a new Aux track, the generated Aux: Aux 1 is also stereo, the Aux input is “Aux 1: Stereo”. If the Aux input is set to “Aux 1: Right (mono)”, the Aux track still appears to function in stereo, that is the stereo meter shows independent Left/Right activity. Is this to be expected and because the Aux track is basically a stereo audio track with a patch point input? Any insight would be appreciated...
