Yes, the decoder does the synthesis packet by packet. But if your application is going to fill your input buffer with only one packet at a time how are you going to take care of the checksum? In Ogg Vorbis only the pages have headers not the audio packets. Which means the check sum is calculated for the whole page. When you calculate the checksum parallely you are already through with part of the page which is not a friendly condition for that application.
