I originally thought that the 'reflections' of Luke standing on the lit-up floor rectangles seen in the glass window, had been added for the 2004 DVDs when they came out....but on checking the GOUT realised they had always been there.
So I personally like this idea of the sabers being 'reflected' subtly too, especially in the shot when Luke is closer to the window after he's recovered from being hit on the head by a flying object. (Having said that, I guess all the 'reflections' could be removed from the window instead, alternatively) Either way, consistency would be good here.
Just how easily seen Luke's 'reflection' currently is, can be seen at the very end of this clip - http://www.youtube.com/watch?v=Qf_IthivGgA
