Ironically, it seems that while pointing out how someone else does not know what they are talking about you have demonstrated your own lack of understanding of the rules. The rules say the requirement is this:
"a high school education or its equivalent, defined as successful completion of a 12-year course of elementary and secondary education".
So - it is possible that someone can have a "a first degree, masters degree,doctorate and PhD" but still not meet the requirement because they did not have the necessary education at elementary and secondary education. It would be a brutal refusal - but it can and has happened. Some COs have accepted higher level degrees - other have insisted on seeing the proof that someone met the elementary and secondary school requirement.
Now - each embassy interprets the rule to their education system, so I am not commenting on whether the case being discussed is qualified or not - just wanted to help you "interpret a sentence or two".
