I can't be sure but aren't you missing this bit (copied from the example)

        var controlOptions = {
            mapOptions: OpenLayers.Util.extend(mapOptions, {
                maxResolution: 156543.0339,
                maxExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34,
                                     20037508.34, 20037508.34)
            }),
            layers: [jplOverview]
        }
        var overview2 = new OpenLayers.Control.OverviewMap(controlOptions);
        map2.addControl(overview2);
