I tend to use those words interchangably, but different from "marked for
recycling".

Yup.  The marking does it.

I was assuming there was only one clone in existence at this point (the
original having been destroyed).  

I've definitely been able to restore from from a clone simply by having
the clone online and the original offline.  It didn't request the
original and I didn't mark anything suspect.

My test machine has only one drive, so I can't easily do all-tape
cloning tests on it....
