If you are on an international itinerary you are not officially "checked in" until you are at the airport and someone has looked at your passport. It doesn't matter if you did OLCI or not. So I would not worry.
I'm looking at the waitlist for my international flight tomorrow and it shows 0 "checked in" in J. And I'm sure that people have done OLCI at this point. There are also no names on the upgrade list yet.
