Here is an update as to what happened after I submitted my primary.
When the cycle began after I submitted my primary, an investigation was initiated as there was an obvious discrepancy between my 2014 application and my 2015 application. An AMCAS investigations specialist contacted me only a day after I submitted my primary about this. I explained the situation to him via email, and I told him that I had obtained an extra "letter of recommendation" from the dean of my alma mater corroborating my story. The AMCAS investigations specialist asked me to have that letter forwarded to him as well. A couple of days later, the investigation was discontinued, and I was home free at that point. Also, keep in mind that I only sent the letter from the dean to schools I applied to a second time. Any of the schools I applied to for the first time never knew about my falsely reported IAs, so I decided against sending them that letter.
I'm very happy I decided to not report those false IAs. Even though I had to deal with the investigation and have an extra letter of recommendation, I had a much more successful application cycle where I was interviewed at 8 schools. I was accepted to 4 schools, waitlisted at 3 schools, and rejected post-interview at one school. I will officially be attending medical school at the Medical College of Wisconsin this upcoming August! If anyone has any other questions about an IA situation similar to mine, I'd be happy to help.
