If it is an Alumni or second year student, it does not mean they feel more interested in you. Probably when he/she fill in the interview report and realized he/she missed something during the interview. (and he/she is really serious about this, does not want to guess).
If it is ADCOM member or even the director of the ADCOM, you should be congratulated. I bet if you make this shot a good one you definitely get in.
