The "ref" is a special case.  See the documentation for the config
schema:

http://mav.sourceforge.net/maverick-manual.html#N105F4

If there is no name, it defaults to the value of ref.

If you only have a single view, you can leave off the name entirely and
that view will be rendered no matter what you return from the
controller.

The redirect view can either look for a path in the static config
(missing in the above example) or it can take the destination from the
controller dynamically (through the model).  Take a look at the javadocs
for RedirectViewFactory:

Factory.html
