yes, I was (and probably still somewhat am) misunderstanding how rdiff-backup works under the hood.

But Adrian's msgs helped me out there (and so does yours, thanks).

ah ha, that's a very useful technique to know (thanks!), because before I had (once or twice) just plain been gunning all the data on the backup disk (rm -rf *), and then doing a backup (which took forever -- 170+ GB over usb2). Plus my fear of having that window of time where my source files weren't backed up...
