Bases Loaded Walk Ends Game (or does it?)

Bottom of the seventh, tie score, bases loaded, two outs. Batter receives ball four. All base runners advance to the next base. But the batter-runner goes about halfway to first and then...

Of course, if she goes into the dugout she's out and no run scores. But what if she stops and comes directly back toward the plate area, lining up to shake hands since the winning run has apparently scored and the game is apparently over.

Does this become an appeal situation for the defense, or is this a situation where the umpire can automatically call her out? What rule or interpretation would cover this?

BR is awarded 1st base. Is there a secret time frame in which s/he must reach 1st base? Is s/he out for backing away from 1B? Has s/he been assisted by anyone in advancing to 1B?

If the answer to these questions is "no", then my partner and I am headed toward the parking lot. The way I'm reading 4.2.1, the game is over at the point the winning run scores. Maybe that could be stated better, but that's what it reads.
