If she's still with OM, then you're right, she's still firmly planted in Replay. Well, shoot, it LOOKED like what I'd seen before, Cyclone..if I'm wrong, I'm sorry.
BUT, she could be spending some time on her own, too. It is common for a person in Withdrawal to be locked within, needing to get away to process.
Sometimes things are not what they seem; and time will tell all, and you'll know for sure.
Sounds like you had a great time with your boys, enjoy them while you can, they grow up far too quickly.
Remember, as each person is different, every MLC/Transition is different..what works for one may not work for another. Most of the time it is trial and error for ALL involved.
