I also just found this video for a steerable tag (not sure if it's ZF since this appears to be the bus mfr's video). I found the most interesting part to start around 2:35 when they show the two coaches in a split screen pulling away from the curb. The rear swing increases, and the turning radius is significantly reduced as you will see in the full lock turn. Reminder, this isn't a Newell product, so things may function slightly differently, but it's a good demonstration of the feature in this model bus.
