It is often useful to use semantically meaningful names on Associations.
In the case of uni-directional Associations, they can also be used to make a quick form of OWL/RDF-like pseudo semantic triple, as used often in the Webel Parsing Analysis recipe for SysML®.
But don't use Association names instead of ItemFlows with exchange items!
If you find yourself repeating a 'name' on more than one Association, it's usually a hint that you need a custom Stereotype and «keyword» to promote Single Source of Truth (SSOT) and Don't Repeat Yourself (DRY). It needn't be a fancy ontology, just collating such custom Stereotypes in a single Profile is often adequate.
