Not sure about why not split them up, but usually there's a requirement that seized assets are auctioned off. Since the government can't treat that bitcoin amounts as currency doing an exchange like that probably violates some rule. I believe that they have to do similarly with any other security (stocks, bonds, etc.) that's been seized.
