No, he is pointing out that get the right answer, each HHH NEEDS to wait 
for the previous one to get the right answer.

But, if to do so, it results in the definition of HHH that just never 
aborts and thus HHH isn't a decider.

You just don't seem to understand the difference between what you 
implement and what is needed to meet the requirements.

If what is needed to meet the requirements is not implementable, then 
the conclusion is that the problem is impossible to do, which is the 
case here.

Your inability to understand this just shows your fundamental lack of 
understanding of the system.
