We swap the word "determines" for "predicts"
When we swap thew word "halt decider" for "termination analyzer" the
above is translated from computer science into software engineering.
The second half proves that this is the H that aborts that is making the
prediction of the behavior of D when emulated by a hypothetical version
of itself then never aborts.

THIS EXACTLY MATCHES THE SIPSER APPROVED CRITERIA The finite HHH(DDD)
emulates itself emulating DDD exactly once and this is sufficient for
this HHH to predict what a different HHH(DDD) do that never aborted
its emulation of its input.

But that different hypothetical HHH is a non-input.

HHH is supposed to predict what the behavior of DDD would be if it did
not abort its emulation of DDD that is what the words that Professor
agreed to mean.

If IT didn’t abort DDD calling its aborting self.

 I don't know how you twist words to get that.
HHH is required to predict the behavior of DDD
as if every HHH had its abort code removed.
 

That is twisting the words. HHH is required to predict the behaviour of its input *without any modifications*. So, the 'as if' is a dream that makes the reasoning invalid. It is not allowed to substitute a dream for a fact.
