Proving that the simulation is incorrect. Because a correct simulation
would not abort a halting program halfway its simulation.
Just for clarity, a correct simulation wouldn't abort a non-halting
program either, would it? Or have I misunderstood this correctness?

A non-halting program cannot be simulated correctly in a finite time.
So, it depends whether we can call it a correct simulation, when it does
not abort. But, for some meaning of 'correct', indeed, a simulator
should not abort a non-halting program either.
OK, thanks!
In other words he is saying that when you do
1 step correctly you did 0 steps correctly.
