Given there are known polar planetary discs, and this orbit seems stable, wouldn't that suggest that polar systems are formed because of some past interaction between the two stars that disrupted them from the original plane of formation?
The planet could be a capture.
Possibly. I didn't dive in deeper to see if they even know the shape of the orbit. From my understanding a capture is very unlikely to have a near circular orbit. But planetary discs definitely aren't captures, so something changed the stars in those.
