SFOvacations earlier posted about award codes and that may be the key. The speculation would be that if the award code doesn't change, then the award doesn't reprice. Any change to region, overall cabin type or award type (standard vs saver and probably OW vs RT) causes the award code to change which triggers the reprice.

From a programming perspective it even makes sense. There is a lookup table with the award code and the number of miles required. If you change award codes (a whole new set has been developed for post 2/3 award apparently) the lookup table points to the new number. As long as the award code stays the same, the table continues to direct the software to the old number.
