I think Glenn's thing is, back pressure would be actual pressure pushing up the exhaust. While you're describing resistance to flow, which is pressure resulting from resistance. Not pressure resulting from some other source.

To develop: the pressure you're measuring is coming from the exhaust gas, while back pressure is not.
