X = DDD emulated by HHH∞ according to the semantics of the x86 language
Y = HHH∞ never aborts its emulation of DDD
Z = DDD never stops running
My claim boils down to this: (X ∧ Y) ↔ Z
void EEE()
{
HERE: goto HERE;
}
HHHn predicts the behavior of DDD the same
way that HHHn predicts the behavior of EEE.

The last "would be" means that the clause is conterfactual.
But why would anybody care about the conterfactual behaviour?
It is not counter-factual.
