I suppose that's another reason why <hn subheading> would be better 
than <hn role=subheading>, because I doubt you would have suggested the 
same "but only if it is a sibling" rule for role="subheading".

How about allowing <Hn subheading> to also be immediately preceding?

(Suppose you mean adjacent sibling[1] and not general sibling.[2])

Btw, I find "subheading" a bit unclear word ... Subhead(ing) sometimes 
means just "a next level heading" or a "level 2" heading. Whereas what 
we are discussing is actually a kind of heading caption ...

So perhaps @hcaption would be a better name?

Regardless: <hgroup> allows the exact same "ambiguity". 
What about subheadings of subheadings?

<h2>heading</h2>
<h3 subheading>subheading<h3>
<h4 subheading>subheading<h4>
