Nope, only to youtr INCORRECTLY simuated by HHH.
In other words you believe that professor Sipser
screwed up when he agreed with these exact words.

If simulating halt decider H correctly simulates its
input D until H correctly determines that its simulated D
would never stop running unless aborted then
H can abort its simulation of D and correctly report that D
specifies a non-halting sequence of configurations.
