This comment is no longer accurate, since Create() now always does something. 
How about just:

  // Creates an insecure content infobar and delegate and adds the infobar to
  // |infobar_service|, replacing any existing insecure content infobar.

[Robert Sesek, 2015/01/27 20:33:21]

Done.

   // an insecure content infobar and delegate and either adds the infobar to
   // |infobar_service| or replaces the existing infobar.
