The only valid rebuttal is to show all of the steps of
exactly how DD correctly emulated by HHH reaches its
own "ret" instruction.
The question whether DD emulated by HHH exists is too uninteresting that
it would need a rebuttal, and so is the question that does it reach its
"ret" instruction if it exsists.
