Secondly in the matter of aria-labelledby for non text content:
- The first example has no alt
- The second one: seldom  is there text taht says '4 out of 5' for *rating it is only the image.
But, yes, the  example is a good one if it is indeed marked up that way with multiple star images and text alongside. 

About use of role=headings:
It appears it is more of a remediation technique to be used only when HTML h<n> cannot be used like for h7 as illustrated?
Need to think of more used cases I guess.

Thanks,
