Expected Behavior:

Actual Behavior:

This one is a bit new. They have a UA detection script, which says:
Android: true but Smartphone: false because it doesn't contain Webkit

//browser
var g_ua=(function(){
    var o={};
    var ua=navigator.userAgent;
    var apn=navigator.appName;
    var apv=navigator.appVersion;
    o.Win9X = (apv.search(/windows 98/i)>-1);
    o.IE = (apn.search(/internet explorer/i)>-1);
    o.Opera = (ua.search(/opera/i)>-1);
    if(o.Opera)o.IE=false;
    o.Safari = (apv.search(/safari/i)>-1);
    o.iPhone = (apv.search(/iphone/i)>-1);
    o.iPod = (apv.search(/ipod/i)>-1);
    o.iPad = (apv.search(/ipad/i)>-1);
    o.Android = (apv.search(/android/i)>-1);
    o.BlackBerry = (ua.search(/blackberry/i)>-1);
    o.SmartPhone = (ua.search(/webkit/i)>-1&&ua.search(/mobile/i)>-1);
    if(o.iPad)o.SmartPhone=false;
    o.iev=-1;
    if(o.IE){
        var re=new RegExp('MSIE ([0-9]{1,}[\.0-9]{0,})');
        if(re.exec(ua)!=null)o.iev=parseFloat(RegExp.$1);
    }
    return o;
})();

which means that later on in the onlinetop.js script we get at

if( g_ua.SmartPhone ){//UAがスマホ
    if(nol.data.smp==undefined||nol.data.smp=='1'){
        location.href='http://www.nhk.or.jp/sp/';
    }
    document.write('<p class="smInfo"><a id="h26" class="beacon" href="#" onclick="return chgSmaphoMode(1);">スマートフォン版はこちら</a></p>');
}

which we never get redirected to.
