    try {
        b = window.external.isGoogleHomePage()
    } catch (d) {
        if (h(a)) return !0;
        var c = google.promos.gpd(a, "mgmhp_hp_url");
        c && g.push(c);
        for (c = 0; c < g.length; c++) {
            var k = g[c];
            if (b = b || a.isHomePage(k)) return !0
        }
    }
    return b
};

They are using the proprietary isHomePage method to check if google.com is your homepage. More info here.
