It *is* a fact that no DDD correctly simulated by any pure function
HHH ever reaches its own return instruction.

Which proves that these simulations are incorrect.

*You don't get to be the judge of this*
As long as the x86 machine language instructions of DDD are emulated by
HHH according to the semantic meaning of these instructions then the
emulation is correct and anyone that disagrees is disagreeing with a
tautology.

They are not simulated correctly, they are aborted.
 

N instructions of DDD[N] are correctly emulated by some HHH[N]
where N is each element of the ordered set of positive integers.

This correct emulation must take into account the fact that DDD is
calling its own emulator: HHH(DDD) in recursive emulation.

Only in so far that it also simulates all recursive calls.
Why is the return of HHH not simulated?
 

The return of HHH is not simulated for the same reason
that the following OutputString("Hello World!"); would
never be simulated.
void Infinite_Recursion()
{
   Infinite_Recursion();
   OutputString("Hello World!");
}
