varian,
You are in the position that I was. They are probably trying to get you to come back. I had a visit like that 6 1/2 years after being DFed. It is the perfect opportunity to get things off your chest. After all, what are they going to do, double disfellowship you?
When they asked me if there was anything keeping me from coming back, I brought up the UN/NGO and pedophilia issues. It was fun to speak to these elders with no fear, as there was nothing further that they could do to me.
Good luck,
JK
PS: I bet they are covering their rears for a new CO's visit.
