Sharepoint 2010: Sign-out even after browser closes doesn't sign the user out

When I sign out of Sharepoint 2010, I close my browser. When I attempt to go back to sign-in, I see that I am already signed in. All of my browser instances are closed.

<script runat="server">

    void SessionAuthenticationModule_SessionSecurityTokenReceived(object sender, Microsoft.IdentityModel.Web.SessionSecurityTokenReceivedEventArgs e)
    {
        e.ReissueCookie = true;
        e.SessionToken.IsPersistent = false;
    }

    </script>
