I Don't know who Yuki is, but i would say that Taking toghether photo at the end of event is a usual practice for decades already, in any multiplayer games at least, like in MMO after a cool raid - or in sandbox games(Minecraft, Garris mod etc) near your creatons. It just helps to capture and preserve good memories.
And especially in vrc! I've been taking thousands of photos through years, after any events that i host at least, many times on other people events
