Why is there a need for more than one long text representation of the
video that is machine-linked to the video?

Sure, there are many different types of long text descriptions that
you can get for a video. But we don't have to link them all
individually to the video. How would we visually present all of these
alternatives? How would we present them to AT?? Instead, if we really
have more than one long text description, we can always pack them into
the HTML page that the long text description link references.

The type of transcription/transcript/whatever that I've been talking
about would contain both a full transcript of what is being said plus
a description of what can be seen.

No different.
