UMLR — Location: Page 286, 12.3.3 Semantics - Nonsensical alternative to stereotype name

An alternative name is given for stereotypes:

"If the ExtensionEnd is given a name, this name can be used in lieu of the stereotype name within the pair of guillemets when the stereotype is applied to a model element."

Earlier, the specification of the extension end name is given as "extension_stereotypeName" so this is a rather bizarre option. When would this ever make sense?
