Bicycles don't have transversely mounted pairs of wheels, so compared to a lorry, any difference in the tracking radius on the extra wheel will be very small. The fact that the bike can be ridden at all means that it will go round corners (you have to be able to lean a bike to balance it) and you can actually see the bike cornering successfully in the video.
I think people are taking this a bit seriously. It's just a bit of fun, not a practical re-engineering of the bicycle!
