Hard to believe as their behaviour is so different and you don't

We all see the differences between these two.

 They both correctly predict behavior that must be aborted to
prevent the infinite execution of the simulating halt decider.
 

Except that the prediction for the second one is wrong. The simulation of an aborting and halting function, like HHH, does not need to be aborted. This is proved when it is simulate by HHH1. HHH aborts after two recursions, which is not an infinite execution.
We know you really, really wants it to be correct. So, you are cheating by suppressing part of the trace, in order to hide the conditional branch instructions in the second case. But no matter how much olcott wants it to be correct, or how many times olcott repeats that it is correct, it does not change the fact that such a simulation is incorrect
