Absolutely - but I think regarding an official statement, the contention here might be that they want players to find this out themselves. It didn't work this time, but if it can work, perhaps they don't want to spoil it for the players by making an announcement.
Like, imagine this (hypothetical) context behind those tweets from Sean.
- Sean sees that two players are about to meet on a stream
- he's clearly really excited about it, so much so that he makes tweets
- the two players meet each other, and it's immediately clear they haven't been instanced together
- Sean feels frustrated/angry, knowing that players can theoretically meet, but that due to whatever reason (NAT issues or server issues), they aren't seeing each other
- BUT Sean knows that in coming days/weeks, other players will see/find each other, and he knows that when that happens, it will go viral
- so he keeps completely silent, knowing that if he made an official statement he would puncture the potential energy behind the discovery, the mystery and discovery would be gone, but he has to deal with vitriol for a while because of it
