I've spent my fair share of years driving trucks. Me thinks this is not what it appears. The truck on the right is a 'rigid' i.e. not a semi trailer, which is the one which moves its line. Unless technology has come a long way in the past couple of years, there is no way you can reverse a semi trailer at that speed in a straight line without constant correction.
Also for both trucks to be able to reverse at identical speeds from take off and to maintain that is a near impossibility. Modern trucks are amazing, particularly Volvos, but i seriously doubt the legitimacy of this demonstration.
Just my considered opinion. I know we have so other truckies in our midst so no doubt some more professional opinions will be coming your way.
Bring it on. Oh. That sounds like an Ice Break ad.
