Disqus footer code prevents static page caching

disqus_footer outputs

$output .= 'var disqus_def_name = '. drupal_to_js($user->name) .';';
$output .= 'var disqus_def_email = '. drupal_to_js($user->mail) .';';

This prevents static page caching strategies for logged in users.
Doesn't disqus maintain its own logged-in/logged-out information via its own cookies?
