It is true. There are partial simulators that do simulate D(I) to its termination (if it terminates) and there are simulators that don't.
That you cannot imagine something does not mean it can't exist.

Indeed, no such HHH exists. This proves that HHH cannot possibly simulate itself correctly.
 "Correctly" means must do whatever the x86 code specifies.
You are in psychological denial causing you to be irrational.
Which means every instruction is followed by the emulation of the instruction after it or the emulaition is not totally correct, and something only partially correct is not actually correct.
After all, that IS part of the definition of the x86 instruction set.
