What doesn't happen is DD reaching its "return" statement
final halt state.

 I hae.

It is truism that simulating termination analyzers
must report on the behavior of their input as if
they themselves never aborted this simulation:

 Right, of the input actually given to them, which must include all their code, and that code is what is actually there, not created by this imaginary operation.
 

In other words every single byte of HHH and DD are
100% totally identical except the hypothetical HHH
has its abort code commented out.

Thus, a HHH that aborts to return an answer, when looking at the DDD that calls it, must look at the unaborted emulation of THAT DDD, that calls the HHH that DOES abort and return an answer, as that is what the PROGRAM DDD is, If you can not create the HHH that does that without changing that input, that is a flaw in your system, not the problem.

or they themselves could become non-terminating.

 But you aren't simulating the same PROGRAM D that the original was given.
 

It is not supposed to be the same program.
*simulated D would never stop running*
refers to a different HHH/DD pair
It is a hypothetical HHH/DD pair where everything
is exactly the same except that HHH has no abort
code.
Ben freaked out that professor Sipser agreed
to my use of the term *would* in
*simulated D would never stop running*
and said that he thought I tricked professor Sipser.
This is all still there in newsgroup servers
that don't keep deleting older messages.
