In what sense does @aria-describedby "figure in alt text"?

As currently suggested in the ARIA implementation guide and in the
HTML to Accessibility API mapping guide, @alt is mapped to the
accessible name of img (accName in MSAA), but @aria-describedby is
mapped to the accessible description (accDescription in MSAA).

What bit of what spec are you thinking about serving as evidence here?
