Page 8:

"Ogg Theora" multiplexes a Vorbis-encoded audio bitstream and a
VP3-encoded video bitstream in a single physical Ogg bitstream. 

I believe this is incorrect as well.  Ogg Theora, to my knowledge, is a
video codec.  It does not have any formal relationship to Vorbis and
does not require that a Vorbis stream be present.  You have a Theora
bitstream and a Vorbis bitstream that are concurrently multiplexed to
provide the video and audio.  It should be possible, down the road, to
use Squish, Flac, or Speex in place of (or in addition to) Vorbis, and
this should have no effect on Theora at all.
