Right. Good logical point. Some people seems to have forgot his clases of ABC
logic in the school. But well, everybody fall in that fallacies some times.  It
is just human. In any case, this is, perhaps, no so a black or white issue: as
far as programs are better and better, they tend to approach a kind of playing
style that makes sssdf list nearer to human elo. Of course, they are still not
coincidental 100%. Maybe 50%?
Hope "coincidental" is a correct english word.
