If is was true that it is not a faithful simulation
then you would be able to show exactly what sequence
of instructions would be a faithful simulation.
If it were false, you'd be able to chop out the unreachable code without any adverse effects. Can you?

I already know the answer.
You have not yet shown that you even understand the question.
I suspect that you don't know the first thing about programming.
What exact sequence of the following machine addresses
of DD emulated by HHH causes DD to reach its own
final halt state at machine address [00002155]
When this sequence is required to conform to the
rules of the x86 language?
_DD()
[00002133] 55 push ebp ; housekeeping
[00002134] 8bec mov ebp,esp ; housekeeping
[00002136] 51 push ecx ; make space for local
[00002137] 6833210000 push 00002133 ; push DD
[0000213c] e882f4ffff call 000015c3 ; call HHH(DD)
[00002141] 83c404 add esp,+04
