clarified plugin capabilities for duplicate identical / different files

In the documentation it is mentioned : 

_(Note that at the moment, the plugin does not check if the files are actually the same or not, it only looks for the same file/class name.)_

This is a bit confusing as the plugin is capable  of printing

- duplicate but identical classes/resources (as per SHA256). 
- duplicate but different classes/resources (as per SHA256). 

So as per my understanding the plugin can check if these files are actually the same or not.
