I think the point is that there could be some meddling to make sure people pass. I am not purporting that's the case I just think that's why it's mentioned. I went to a school that was nowhere near Harvard level and saw it regularly, people sleeping in class or who didn't do a single assignment who still graduated with me. I think it was a money thing. Still not saying that's happening at Harvard just that it wouldn't be the most shocking thing. That said, I agree with other commenters that you set this situation up with the rigorous acceptance criteria. You're testing the people who got into one of the best schools so presumably if your selection criteria works they should all excel at the courses.
