As far as I understand, specifying build/plugins/plugin/**extensions set to true allows plugins embedding a components.xml to actually declare these components as part of the context. In such case you don't need to repeat the plugin declaration in the build/extensions/extension section.
The build/extensions/extension is rather used to include jars (non-plugin) that declares additional components. In the example you gave, the plugin and the artifact declared in build/extensions/extension don't have the same coordinates, so they have likely different purposes.
