NAVYgreg, I don't know exactly because I am NOT a RD, but I do know what he's done for us/candidate and our/his application process. Our RD has been there for us, helping when things got stuck for any reason. I won't say they are all the same but I do believe they all have the same goal, that is to get the best students interested in an education at USNA and to assure those applicants are properly aligned and represented in the admissions office process. It isn't an easy process and they know that. There are many factors outside the applicant's ability to control, and they know that too.
That said, knowing what I know, and if I received that message, or if I were you, I would respond to the email as soon as possible with a message that you will like to call to speak with him/her and something nice about how you'd rather speak to them regarding those questions AND THEN CALL the admissions office and make all attempts to speak directly with that person (there's always study hall, after hours, at home, ect. you can find the time). I think replying to an email might be "enough", but if your really interested in a spot in the yard, I'd call and look at this opportunity as a second level BGO interview.
I'm guessing here that he/she feels there are a few things that are left uncertain by your BGO's record and/or in your application that could benefit from further exploration. You already have the questions and the advantage of time to consider a thoughtful and honest response. The discussion could yield additional questions and conversation that will let the RD understand the PERSON they are speaking with. Be yourself. And good luck. Sounds like a great chance of presenting yourself to the Academy directly.
