You mean a crazy rule like, since the SIC type rating doesn't qualify you for anything in the US, doesn't require an "authorized instructor" for the training and doesn't involve showing anyone that you can fly anything, it doesn't count to reset the FR clock?

No, there has be no specific ruling to that effect. But the odds are pretty good that's the position that the FAA will ultimately take.

Play it safe. Get the flight review endorsement from someone authorized to give it to you.
