Note that this 'link' also include 'hierarchical mapping links' since 
skos:broadMatch is made a suproperty of skos:broader (which means that 
every assertion of skos:broadMatch entails one assertion of skos:broader).
Somehow I feel like your text also fits the situation, even when the 
interpretation of 'hierarchical link' is made a bit different from what 
it was.
But I wanted to flag the issue to people of the SKOS mailing list which 
might not have noticed this new resolution, eventually to get feedback 
from them.
