Fingerprinting scan check done on two people for one full time job

Hi so last week I completed a fingerprinting scan appointment for a full time job with the San Francisco Municipal Transportation Agency after interviewing a few weeks prior. I was told at the interview that two people would be contacted for background checks but that only one person would receive an offer. They took my employee photo at the appointment in addition to performing a fingerprint scan. I was wondering if anyone else has had a similar experience in terms of this and how these situations would work out if I end up being only the second choice. Thanks to anyone who can give insight.
