augmentSQL seems to empty fields from object

I'm developing a simple module to provide 'soft' scheduling of pages (Embargo & Expire, I'm aware this is also provided by the workflow module). For this I wrote a SiteTreeExtension which adds Embargo & Expiry as Datetimefields.

I'm trying to implement augmentSQL on this in order to filter out pages that are under embargo/expiry. But any time I add an extra 'Where' clause to the augmentSQL method involving the Embargo or Expiry fields, the 'Embargo' and 'Expiry' fields of all resulting Pages appear unset. If I comment out the 'addWhere' lines, these fields load their data just fine.

Am I missing something?

class EmbargoExpirySchedulerExtension extends SiteTreeExtension {
   public static $db = array(
      'Embargo' => 'SS_Datetime',
      'Expiry' => 'SS_Datetime'


   function augmentSQL(SQLQuery &$query) {
      $myclass = $this->owner->className;
      if (is_subclass_of(Controller::curr(), 'ContentController')) { // on frontend
               "\"{$myclass}\".\"Embargo\" IS NULL OR \"{$myclass}\".\"Embargo\" < NOW()",
               "\"{$myclass}\".\"Expiry\" IS NULL OR \"{$myclass}\".\"Expiry\" > NOW()",
