Just go to the event and see for yourself. It'll be all day tomorrow.
Basically you enter the lobby area and you will be randomly matched with someone else in a 1-on-1 room. You can then talk to them for 5 minutes before you're teleported back to the main area, and then 20 seconds later you all get matched with a random person again.
It's a great way to talk to people 1-on-1, a great way to meet new people, and a great way to catch people away from their usual circles.
