No, he doesn't.  Whoever is in control of making changes to the page 
should be sufficient, even if they weren't the original author of the 
page.  Optimising for edge cases is not a reasonable thing to do.

Besides, if the aim is to check the how appropriate the alt text is for 
a page, then it doesn't matter what the HTML5 spec says.  Evaluating 
accessibility is a largely non-machine checkable exercise and trying to 
grind the conformance criteria down to a boolean yes/no answer that can 
be offered by a machine does little to improve accessibility.
