After the replacement, the two <PASSWORD> elements have the same content:

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var user1:XML = <USERDETAILS>
            <LOGIN>joe</LOGIN>
            <PASSWORD>linuxRules</PASSWORD>
          </USERDETAILS>;
          
        var user2:XML = <USERDETAILS>
            <LOGIN>ken</LOGIN>
            <PASSWORD>default</PASSWORD>
          </USERDETAILS>;
        
        trace(user1);
        trace(user2);
        user2.PASSWORD = user1.PASSWORD;
        trace(user1);
        trace(user2);
        
        trace(user1.PASSWORD[0] == user2.PASSWORD[0]); // Displays: true
        
        trace(user1.PASSWORD[0]
