...a QDR is a bearing to the station no matter where you are heading


The QDR is the magnetic bearing from the station. A QDR from an NDB is "the same as" a radial form a VOR. A QDM to an NDB is "the same as" an inbound course to a VOR.

The track (or "position") of QDR 190 is exactly the same as QDM 010.

And, as you say, this is irrespective of the aircraft's heading or direction of flight, but it applies both for QDMs and QDRs.
