Combinator selectors are not class selectors. The use case is that it tells you if that class selector is used but not listed as found in a stylesheet, then you know it is only part of a descendant class or other combinator or a misspelled classes or otherwise non-defined class.

In other words if your p.author class was in a div of a different type or nested in some other way, it would not be used at all since the p.author class is not in and of itself defined.

If you use a class selector and define it, it will be found.

So yes, looking at that report will show you which class selectors are defined and where. The CSS Selectors report where tell you if a defined selector (of any type) is used.

Using these reports can help you track down issues with classes.

You can export these reports to csv and merge them as needed.
