Unvortunately I can't agree with what you say.
HHH terminates,
os DDD obviously terminates, too. No valid

The directly executed HHH is a decider.

What does simulating it change about that?

PATHOLOGICAL RELATIONSHIPS CHANGE BEHAVIOR

How? What is pathological?
 

void DDD()
{
   HHH(DDD);
   return;
}
That DDD calls its own emulator (a pathological relationship)
makes this DDD and HHH stuck in infinite recursive emulation
unless the outermost HHH aborts its emulation at some point.
Whether HHH aborts its emulation at some point or not DDD
never reaches its final halt state of "return", thus DDD
cannot possibly halt no matter what HHH does.
When HHH sees this it aborts DDD and correctly reports that
it emulated DDD is non halting.
