Interesting Situation

Baseball 'Gimmick' Play

First off, I seriously doubt that the runner on 2nd came up with this on his own. That said, I live and work in games in this area, and I can just see other coaches attempting this now, so a couple of questions -

1) Once the throw went to 1st, shouldn't the home plate umpire moved into position to pick up that runner coming to third? While it may be a little late to get the actual touch if the runner was moving on the pitch, he certainly would be able to tell if the miss was blatant.
2.) What do you do if you see this? As this article says, its hard to tell who intended to do what, so I would have a hard time ejecting anyone for this. I guess we just have to treat it as you would any missed base, even with this article being the talk of the baseball town.
