    Switch between <code>Route1</code> and <code>Route2</code> with <code>$state.transitionTo('state', {}, false)</code> still causes location to change.

  <p ng-show="$state.current.data.correct">
    The correct version uses <code>$state.transitionTo('state', {}, {location: false})</code> demostrating the correct behavior - no location change.
