It certainly does give the Chiefs options.
With Orton being a restricted FA he could warrant some interest from other teams, and the Chiefs would get compensation if he signs elsewhere (possibly a 2nd or 3rd rounder) The Chiefs may not want to give him the "long term" contract if might want.
Then you look at Cassel, if somehow they get Orton locked up for a year or two, now Pioli may look to shop Cassel around for draft picks or players.
So there are two scenarios that could allow us to get compensation for the situation we are in.
I thin you might still see us draft a QB, regardless of if 1 or both QBs will be here next year.
Or there's a possibility of Both being back next year. It's definitely something that will warrant some action in the off season.
