I think you are coming dangerously close to muddy semantics. Let's say: a clone is a clone- git clone, hg clone, etc. A rewrite may start with a clone, but the code is no longer a clone when you start the rewrite. A refactor is a subset of a rewrite. Now we can have meaningful discussions about them.
