Frankly, I think it was either a joke or a marketing ploy to get people to buy the DVD of a movie that just didn’t do so great during its theatrical release.
First, it doesn’t really fit with the rest of the movie. Secondly, it is a dead end. I mean, it would be one thing to have them lose, but it’s something else entirely to have them lose and have the film just end right there. No follow-up, no real reaction from any of the main characters (apart from a few moments of celebration and dejection)? It was also set up by several elements earlier in the film - where Rip Torn gives Vince Vaughan the scarf, and were Stephen Root is telling another team member about the rules around double faults. The whole lesbian pay-off wouldn’t be there. The resolution of the Pirate guy wouldn’t be there.
I am hopeful that it is just a joke.
