We do know that is a proprietary locking mechanism to lock the wheels together. This could potentially fix the angle between front monofork and rear swing arm. There may also/alternatively be robust limiters in the rear helical hinge. The front hinge looks like the weak spot in this scenario.
Then again, how much actual weight is going to be acting on the whole folded set up.
To handle the forces, a rotational locking device at the axles would be noticeably large & inefficient, & it would likely not be a passive device. The hinges are too small do handle rotational locking. Even the swing arm impinging against the bottom bracket would yield higher forces than I'd be comfortable with. I'd consider a stop on the frame extending down to touch the swingarm or axle/hub, thereby limiting motion passively & with low forces. I suspect they've figured out something more elegant.
Thinking more about it, a stop attached to the brake side dropout could work well. It could be short, light & unobtrusive.
