I actually applied to both and only received a secondary to 1 (today). I called to find out and they told me that you are only offered a secondary to 1 school if you applied to both, the one the committee feels you will be a better fit at.
The problem I'm facing now is that I had no idea about this and got a secondary to the campus I'm a little less interested in. So I don't even have a chance at the other campus.
