How is this possible with quattro?
Since the Quattro drive system is purely mechanical, that center diff and possibly the transmission are completely shot. We all know that the Torsen center diff is limited slip, but that's it, it is limited, not open. Same thing with my Miata (which has a Torsen diff) you can turn the wheels by hand if you're not applying any real torque, but dragging the car along behind the truck is way too much for that diff to handle. You can safely do a four-wheel tow for a few miles, or you just flatbed that car. Anyone who thinks that is a safe way to tow your Quattro enabled car does not deserve to own one. Being in neutral does not disengage the Quattro system, it only disengages the transmission from the engine. Removing the driveshaft would allow you to safely two-wheel two that car, and let's hope that's what they did.
I would say someone f'ed up. They certainly wouldn't go through the trouble of disconnecting the driveshaft since there are two other FWD cars on the truck already. This guy is just a dumb truck driver and has no vested interest in the cars- just needed to get them from one place to another. I wish Paul Harvey would tell us "the rest of the story"....
If anyone hasaccess to a system that can track down tag numbers,i'd print this out and mail it to the owneras a public service. But at the same time, given there are 4 different types of vehicles on this flat-bed, thiscould bea repo job, in which case that point is moot.
"How is this possible with quattro?"
Disconnect the driveshaft, that's how it's possible. It doesn't put any more wear on it than flat towing any other vehicle.
But I'm guessing the driver didn't think, cause the car with the lowest rear bumper is being towed at an angle to kill its own rear end.

I agree that the only way to do this is "rear driveshaft removed".
If that was not done the poor Torsen is being pushed beyond its bias ratio and differentiating as a heater. The element gears would be spinning at 2x the wheel speed, the washer packs on the side gears would see excessive thrust loads, all of which would result inHEAT,scored element gear pins, scored washers, and scored gear faces (element and side).
If the Torsen didn't weld itself together, it would surely not perform the same as it did before the tow.
I'm of theopinion that the driveshaft was not removed, the tow driver is clueless regardinghow "quattro" drivetrains work, and unless the car is being repossessed the driver should be very unhappy. If somene can track the plate number, that VIN record should have a note that it was drivetrain abused.
