events and documentation

yes,I found these too;
And I found other bugs:
if there have three textarea in one page,the name like editor1,editor2 and editor3;
the first editor,editor1 fired the event:

     'editor.on pluginsLoaded'
     'editor.on instanceReady'
     'CKEDITOR.on instanceReady'

the second editor,editor2 fired the event:

      'editor.on instanceReady'
     'CKEDITOR.on instanceReady'
     'CKEDITOR.on instanceReady'

the third editor,editor3 fired the event:

      'editor.on instanceReady'
     'CKEDITOR.on instanceReady'
     'CKEDITOR.on instanceReady'
     'CKEDITOR.on instanceReady'

Why the event pluginsLoaded only fired once only??And
why the CKEDITOR.instanceReady fired many times????

how to set the pluginsLoaded event be fired each instance ready???

thanks
