off-topic: P.T., if I understand you correctly, in swf9 the "this" that is present when a function is defined is what gets used when the function is executed? I've never seen a browser JavaScript implementation do that -- it seems that would break the language in some pretty fundamental ways.
It _is_ a deviation from Javascript. It is a Macromedia extension (perhaps taken from the Javascript 2 proposal?), specifically intended to eliminate the need for delegates. It applies to closed over methods only. Cf. http://labs.macromedia.com/wiki/index.php/ ActionScript_3:overview (and search for 'closure').
