only the first recorded track online will be recorded propperly, as I understand it. If you join other servers etc these recordings will be bad, like you see your plane is taxiing into the grass on ground and there are stick movements and thrust usage as if it was in the air (which it originaly was).
Ive experimented with this to use Tacview and learn from each online flight, where I had to exit the multiplayer.exe after each flight (I could respawn in that same game tho) to get the record/track running propperly.
Edit: I dont know if this will answer your question, but hope it helps.
