[Boost-build] msvc "default" version

The msvc toolset allows to write:

     using msvc : default ;

the code in question is:

        case "default" :
            configure-really : $(options) ;

        case * :
            configure-really $(version) : $(options) ;

so specifying 'default' amounts to specifying no version at all. Why is 
using 'default' better, or when it's needed?
