But since the simulation was aborted,

complete.
When HH correctly simulates N steps of DD it is incorrect to say that
these N steps were incorrectly simulated.
machine is not in a final state, even if it was correct up to that point.
It also matters what steps where simulated, not only if each was correct.

There are an infinite number of different HH/DD pairs specified by that
template. One class of them simulates N steps and one class of them
simulates ∞ steps. Some of them play a game of bingo before simulating
any steps. Some of them play a game of chess after simulating N steps.
