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.
