Here's human drivers navigating in a similar way in a large intersection in Addis Abada (Ethiopia), I envision white light basically enabling this: https://youtu.be/VPbUpdmAfck
What is actually being enabled, and is it more efficient than a regular green-yellow-red intersection? If you watch on 1x, this seems like a horribly slow/inefficient intersection.
And yes, it looks kinda normalize when the people walking are walking, not running.
