Your 2004 points will expire on Dec 31st, in any event.
I agree with the above posters, since it is one reservation MS will treat all the points the same. If you cancel one of the dates, the points returned will be 2005 points, since they use the 2004 points first.
I don't think you really need to worry about this as long as you don't cancel the whole trip.
