Do note that the folding hinge of the rear stays is also helical in design. That's where I suspect problems will arise in the mid-long term from wear and tear. But in any case, the proof will be in the putting, when the bike eventually gets delivered.

With appropriate sealing and surface treatment, it is possible to make a durable and problem free helical slide/rotation joint. Just whether its done or not remains to be seen.
