What I think is that they are abusing the part of the client which permits this functionality to produce it by manipulation. It shouldn't be too difficult, after all it was only 4-5 years ago that it was possible to move walls and even only 6 years ago that you could force another player to cast a spell by packet manipulation. There are numerous explanations for the latter part of your post, one of which is simple lag. It's possible that he actually appeared on your screen but your client just didn't update when he was on screen, or maybe he managed to sneak in when you weren't looking...
To reproduce the login effect he simply reproduces what a connection fail would cause "Server not responding" which doesn't affect your backpacks or anything open, but it looks like you just relogged.
