My points are this-

Just because we call it an "Ornate", doesn't mean that it's genetically the same as my neighbors "Ornate"- even if they APPEAR identical.

In crossing of an "Ornate" and a "Cranwell"- there could be 2 offspring, from the same clutch, same parents, wich share zero DNA. Thus- The term "Orwell" would become moot, since it could be used to describe 2 specimens that have 100% different DNA.

Now of course these last 2 posts of mine are simplified, but 100% accurate and true.
