I ran my 50i on lift briefly and the front wheels turned slowly and traction message came on. I had not turned anything off. The video linked has no info so it may have reached an apply criteria like you found before the video started.
The AWD systems around with wet clutch T cases have varying strategies and some variation occurs on performance versions vs lower output engines. The general method is very low or no apply pressure on the clutches until engine torque rises, throttle apply rate is great, or wheelspin is detected. If the secondary drive (front end in this case) is applied in turns when unneeded then shudder or clunks are likely owing to speed differences of the 4 wheels and T case clutch trying to make the two ends of car go the same speed.
