Seems odd...
My guess would be on one of the three following:
- Error in your steam cache, making it think you're missing files and re-downloading them even though you have them.
- Full Disc, game was just 2GB too big to fit on the disc so they added that as an online update. Unlikely though.
- 'Subtle' DRM, simply force the user to download 2GB of vital data and you make piracy somewhat more difficult.
