angular ui router- urlRouterProvider otherwise redirection

It seems like the $urlRouterProvider.otherwise('/') only works for url which consist 1 segment only i.e will be redirected to if abcdefg is not defined as part of the state.

But something like or and so on (url with more than 1 segments ) won't get redirected to

Does the $urlRouterProvider.otherwise only works on url with 1 segment only?
