Yeah, I think I agree that you would need to make sure that the
other side does not use the revision marked with :2, once you retire
the object you originally marked with :2 by pruning.  Shouldn't the
second export show :1 and :3 but not :2?  It feels like a bug in the
exporter to me that the mark number is reused in such a case.
