This is true. However, if you are aiming for IM, for example, and you have a ~240/240 for your USMLE, and you interview with:
Hopkins, Penn, UChicago, Cook County Hospital, UCLA-Harbor, Lenox Hill Hosp, MassGen, Loyola University Medical Ctr, Stanford University Hosp, Stamford (CT) Hospital, North Shore University Hospital, UTSW, Brown/Rhode Island Hospital, Vanderbilt, University of Florida, Washington Hospital Center, and WashU, but then your ROL looks like this:
1. MassGen
2. Stanford
3. Hopkins
4. Penn
5. UTSW
6. UChicago
7. WashU
8. Vanderbilt
9. Brown/RI Hospital
but you don't include the community programs like Loyola, UCLA-Harbor, Lenox Hill, NorthShore, even at the bottom of your ROL, then you aren't doing yourself any favors at all. You're being over-confident with the ROL, and the match can only be done "in favor of the applicant" to the extent to the total # of programs that will rank the applicant. "In favor of the applicant" just means that you will get placed to the highest priority program on your ROL that has also ranked you. So, if, according to the above sample ROL, at the very least Brown has not ranked you, then the other programs won't even be able to recruit you because of their exclusion from your ROL, even if they were your last choice programs.
