That is actually a nice fold and it doesn't look like it requires any welding at all for the joints and it is machined into the individual parts leaving a very smooth finish on the main frame without a bulky joint. That alone saves easily a pound or so not needing those giant folding plates to weld onto the ends of the frames also less room for welding errors too. This is a different fold from the birdy or brompton I wouldn't even call it similar just because the wheel folds in vertically instead of sideways (bromptons still have a sideways fold at the front while the birdy mainframe doesn't fold at all). There's only soo many ways to fold a bike. The beauty of this fold is if you forget to put the safety latch the bike would still be very stable because your weight alone is actually keeping it together. But yeah good to see the big manufacturers moving forwards with new designs.
