Irrelevant text ignored. You talked about x86, therefore continuing to talk about x86 is not a change of subject.
I know you have difficulties to recognize the truth, so I do not feel offended, because: 'Don't assume somebody is wilfully wrong, if incompetence could be an explanation, as well.'

 Correctly is measured by the semantics of the x86 language.
This specifies that when DDD is correctly simulated by HHH
calls emulated HHH(DDD) that this call cannot return.

Yes. This shows that the simulation is incorrect.

 You smash a bottle on the ground. No matter how much you
want the bottle to hold water it will not hold water.

Similarly, HHH cannot possibly simulate itself correctly, no matter how much you want it to be correct, it is incorrect. It always aborts too soon and therefore misses the fact that the simulated HHH is one cycle away from its abort and return.
That is supported by the fact that you admit that the simulation cannot reach the return. That makes it incorrect! The x86 language specifies no abort. In fact the hardware simulator of the x86 code (the processor of your computer), shows that the correct simulation reaches the return.
Also other simulators correctly show that HHH will return. Only HHH itself in unable to simulate itself correctly.

 

That is what the semantics of the x86 teach you.
There is no disagreement about the semantics of the x86, if you see that it means that HHH cannot possibly reach its own 'ret' instruction, therefore, the simulation cannot possibly be correct.

A correct simulation is what-so-ever-the Hell that the x86
machine code of HHH/DDD specifies even if this code starts
WW III. Correct is not measured by what you would like to
see or what you expect to happen. Correct is only measured
by the behavior that the code specifies.
 When I say that 2 + 3 = 5 you are not free to dislike this
result and prefer or expect 2 + 3 = 7.

But you seem to reason like that. The simulation is incorrect, but you prefer it to be correct. It is just as wrong.
The x86 doe not specify an abort. If the simulation of HHH is not aborted, HHH will abort and return. That is shown by several simulators.
Only HHH itself cannot possibly simulate itself correctly. That is true, no matter how much you want it otherwise.
Repeating how you wish it to be, does not help. Repeating 2 + 3 = 7 a hundred times does not make it true. Similarly, repeating that the simulation is correct does not make it true.
The problem seems to be that you think you are infallible. So, you don't think about what we say, you just ignore it, because you think you cannot make an error. Then you repeat your claim without any evidence or proof. You seem to think that everything you wish is true. If you want the simulation to be correct, than it must be correct, without any evidence. If, not than you simply redefine the meaning of correct.
You even quote other people, like Sipser, as a support, even although they know that your simulation is incorrect, and therefore they do not agree with you.
