Well, it's pretty clear from the article that a significant chunk of the 'test drive' occurred off road.
And it only makes sense that regenerative deceleration with a motor at each wheel would provide much more granular control when crawling over rocks or other loose surfaces than a friction brake system would.
Other manufacturers of conventional off-roaders have had to design and implement 'hill descent control' systems to serve this very purpose; using the brakes individually to provide a controlled descent.
With a driver pressing on a brake pedal, equal force is sent to each wheel, which may cause locking on one wheel (and thus loss of braking force), and increased demands on the other wheels, which might lead to locking/slipping and a loss of control. Anti-lock brakes aren't really designed to solve this; they pulse the brakes at that wheel to un-lock them, but once they decide the wheel is turning again, they'll allow it to lock right up again.
The Adventure Journal review is a bit more in-depth from someone perhaps a bit more experienced.
