It is not entirely true, as long as we have the front differential unlocked, the same force never acts on both wheels. It is solved by the self-locking differential on the 1000R model, and by the BTC system (using ABS) on the 1000 T model (T3b category). If I lock the front differential (I activate Visco4lok), exactly the same force acts from 0 km/h on both wheels and they are firmly locked (for the 1000 T model (T3b category), ABS is also deactivated when we engage Visco4lok)
This was for demonstration purposes, the goal wasn't to make it over the obstacle, but to show the difference between the locked mode of the 4Lok system vs the limited slip QE Visco Lok that comes with the regular Can Am Outlander models. That is an XTP model, and the XTP model has this 4LoK locking differential feature. Notice how the front two wheels were spinning the first time, then he switched it off, to show how the tire on the left side in the video wasn't spinning, once it sensed the tire on the left side in the video was spinning, the 4WD system ( Visco Lok QE ) sent power to the tire on the left for traction. The tires spinning was intentional to demonstrate this, but your correct some tires would have gained traction, without the 4Lok feature, but that wasn't the purpose for this video, I'm pretty sure. It's Can Am's locker system for the front differential. Visco 4Lok
