H can abort its simulation of D and correctly report that D

DDD is correctly emulated by HHH according to the x86
language semantics of DDD and HHH including when DDD
emulates itself emulating DDD

HHH correctly determines that never aborting this
emulation would cause DDD and HHH to endlessly repeat.
So, the abort is premature. It skips the last few instructions of the program, hiding in this way that the simulation would halt.--
In other words, HHH cannot possibly simulate itself correctly.
Olcott really, really wants it to be correct, but he has no evidence for it, but he thinks that ignoring the errors that have been pointed out helps. He also thinks that repeating many times without evidence that it is correct will make it correct.
He keeps dreaming that the HHH that does not halt, plays a role in the simulation of a HHH that aborts and halts.
But dreams are no substitute for fact, nor for logic.
