Hello,
 
If I understand well, the headers structure in the figure, details
elements is separate and does not belong to the structure of the page. 
However, I wouldn't prefer to have many H1 in one page, For instance: 
 
How would be the order of the headers in Example 2.4
http://dev.w3.org/html5/alt-techniques/ 
if the longer text alternative contains headers?
