That's a rather pithy way to interpret what was said. Here's an alternate interpretation: be different from all the other applicants. If you have the same grades, the same extracurriculars, and the same things to talk about in an essay, you're not going to be different from everyone else and thus won't get in. And that's the nature of being different - you can't quantify it until you see it.
Having gone to a high-percentage Asian high school, I can tell you that traditional Asian parents mostly push their kids to do a limited set of things (high academic scores, orchestra, etc.), which can easily lead to a homogeneous pool of applicants.
Faust is saying that if you want your kid to get into Harvard, you should instead encourage them to do things that set them apart from the thousands of other smart kids applying. Build an airplane, climb a famous mountain, invent something, be a sailor, race sled dogs, etc. Those are the things that make an applicant stand out.
the point is that holistic can be easily used as a cover for race based discrimination and that this is what is happening at harvard and elite universities. when you look at the quantitative disadvantage for asian applicants in terms of SAT/GPA, I think it's clear that homogeneity cannot explain this away. it's also a little absurd that they publicly place so much emphasis on diversity and "interesting" applicants when the actual student body of ivy league colleges is filled with bland wealthy strivers of all races.
the interpretation in your last paragraph is even worse in a way for faust and harvard: only children with the right parental financial resources and support would have been able to "Build an airplane, climb a famous mountain, invent something, be a sailor, race sled dogs" before the age of 18. it is also hard to see why an academic institution cares so much about such things.
