There has been no confirmation from the organizers that they intended to even depict DaVinci's "The Last Supper."
The only reason Christians (or heck the world) has a "unified" vision of The Last Supper is because of DaVinci's painting even though there are numerous other depictions that look very different. It became so recognized and so famous that it got connected with the event but for most of the world, it's simply a work of art.
The actual painting has been redone, remade, remixed and satirized thousands of times before last night.
I think the only reason people saw a resemblance (again, not confirmed other than to say the intent of the ceremony was to be inclusive and not mock) was because the camera focused on Dionysus, the God of wine making, in the center and on the table with people behind him. However, other angles showed there were people all along both sides of the table/runway. I've seen other interpretations of that scene to be a Bachialia. And given the fact that "Festivite" (Party) is captioned across the scene, I think that's an interpretation to consider. That differs from DaVinci's painting.
