I just tested, and you are right, somewhere along the way it started forcing it to a stereo track. Both channels are exactly the same when done this way, so you *could* then split that stereo track to two monos, keep one mono and delete the rest of the litter you don't want.

I don't see anything that would make it easier if you really need the mono track.
Wonder when it switched to forcing a stereo track? I know it used to do mono when requested...
