To my knowledge those seats will only be available to non-elites at the airport at time of checkin.
I always book emergency exit when i can and elites have the ability to book them online. I also noticed that when i booked my last trip on AA it also blocked the seat next to me which is standard with elites (even in emergency exit).
I tried to get my cousin emergency exit seats on a flight to CCS but was told I had to be flying in order to get it for him. He has no status and I am Gold. The agent told me those seats are held for elite members.

Good luck getting your seats.
