everyone else has trouble with construction details like that, so unless he's hiding some structure I assume these frames have a limited lifetime. OTOH, Bike Friday has very similar construction and few issues, so maybe I'm wrong. Of course, limited lifetime in this case might be 10 years instead of 50, who knows?
