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.

 Why do you say that? That is EXACTLY the definition of Correct Emulation.

WELL INDOCTRINATED FALSE ASSUMPTIONS ARE NOT TRUTH.

WELL INDOCTRINATED FALSE ASSUMPTIONS ARE NOT TRUTH.
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.
