No, you've misunderstood (I think).

I run a daily rsync from machineA/dirx to machineB/dirx.  Then I run
rdiff-backup on machineB from dirx to dirxbackup.

So from rdiff-backup's point of view (if rsync is set up so that dirx on
machineB is a genuine *mirror* of dirx on machineA) it just looks as if
the files in question have been deleted by the user (or whatever).

I'm not using rsync to copy the rdiff-backup archive.
