Clarify "10.4.1. Event parameter of an observer method"

10.4.1. Event parameter of an observer method:

If the event parameter does not explicitly declare any qualifier, the observer method observes events with no qualifier.

10.3. Observer resolution:

An event is delivered to an observer method if:

• ...
• The observer method has no event qualifiers or has a subset of the event qualifiers. ...

I find this quite confusing. The statement from 10.4.1 should be either removed or reworded. In fact, the observer method with no qualifier observes events with any qualifier.
