UMLR — Use of Qualifier and Qualified in same section of UML 2.5 spec should be more clearly disambiguated

In Section 9.5, there are several statements mentioning "qualifiers"
e.g.,
A Property that is a memberEnd may itself have other Properties that serve as qualifiers.
and
The notation for qualifiers is defined in 11.5 Associations.

However, there are several statements mentioning "qualified"
e.g.,

• 'subsets’ <property-name> means that the Property is a proper subset of the Property identified by <property-name>, where <property-name> may be qualified.
• ‘redefines’ <property-name> means that the Property redefines an inherited Property identified by <property-name>, where <property-name> may be qualified.

I suspect they are discussing different things. A qualified name vs an association end qualifier.

Please have mercy on us and make the usages clearer.
Thanks
