Does Harvard compare RD applicants with early admits?

2 of by best friends of 17 years are applying to Harvard RD, and I’m afraid I ruined their chances of getting in by committing to Harvard early (before I knew they were applying)
We’re in the same school, international from an underrepresented country and have very similar ECs. Would Harvard compare their applications with mine and decide that we’re too similar?

Maybe. Harvard limits the enrollment of international students to about 10% to 11% of an incoming class (about 160 to 190 students per year). And if you’re from an underrepresented country, Harvard may not admit many students each year from your country – so you may have the one slot open, or they may consider taking more students from your country and less from another country. The only people who know are going to Admissions Officers, and AO’s don’t hang out on College Confidential.

Well, some do. Not Harvard ones AFAIK, but even if they did, they would never give a definitive answer on this forum.
