Explanation of default value for useAllReactorProjects is at best confusing, possibly wrong

See page: http://maven.apache.org/plugins/maven-assembly-plugin/assembly.html#class_moduleSet

The explanation of useAllReactorProjects is given as follows:

If set to true, the plugin will include all projects in the current reactor for processing in this ModuleSet. These will be subject to include/exclude rules. Default value is true. (Since 2.2)

Default value is: false.

I'm using Maven 2.2.1, so I assumed this would default to true. However, it appears to be false. Attached is a small example project which seems to require useAllReactorProjects to be specified as true in order to build correctly with Maven 2.2.1.
