My guess is that it’s mostly due to added weight (saw up to 5.5 tonnes in one video, or 12,125 pounds). Previous largest of this model was 7.9 meters, or 26 feet long and has single rear wheels and single rear axle.
Also, these motorhomes are built much lower to ground, so if built longer with single rear axle, the longer rear overhang would make it easier to scrape on driveways, curbs, or wheelbase to hang-up over tracks, etc....
It uses an advanced motorhome-specific chassis, so ride and handling quality should be to German standards (for a motorhome). Regardless, I like the appearance of tandems a lot, although I would want a shorter version anyway which would have a single rear axle.
Short video shows double-floor integrated chassis.
