The two HUMMER EVs in this video are pre-production test vehicles. As shown in the video, 4-Wheel Steer could help make really tight turns and even maximize tire contact for traction when rock crawling. It's worth noting how it squats down under hard acceleration at the end — no doubt when the air suspension is sorted, a lot of that will be dialed out.
