It cannot possibly return, because HHH aborts itself one cycle too early, showing that the emulation is incorrect. If that is over your head, try to learn how x86 instructions work.

A "Correct Emulation" is one that produces the same result as the program at the input.

Which can only possibly occur be disregarding the semantics

Why do you say that? That is EXACTLY the definition of Correct Emulation.
  WELL INDOCTRINATED FALSE ASSUMPTIONS ARE NOT TRUTH.

And denying definitions is just lying.

 void Infinite_Loop()
{
   HERE: goto HERE;
}
 void Infinite_Recursion()
{
   Infinite_Recursion();
}
 void DDD()
{
   HHH(DDD);
}
 Every C programmer that knows what an x86 emulator is knows
that when HHH emulates the machine language of Infinite_Loop, Infinite_Recursion, and DDD that it must abort these emulations
so that itself can terminate normally.
 SO THESE THREE INPUTS DO NOT FREAKING HALT

No, DDD does halt if HHH is a decider and HHH(DDD) returns.
The fact that HHH need to abort its emulation to be a decider doesn't mean it gets to be wrong about the question put to it as a halt decider.
It just shows that Halting is not Computable.
