Well, obviously in the second shot, the blue has turned green on R2-D2 and on the 3 panel lights at bottom of shot, Luke's pants are no longer sandy/olive, the chess pieces change colour and many other colour problems appear. So the original re-wire does fix the sabre, but screws up the colour in the shot altogether.

The last shot is more subtle, but still mistimes the entire frame.

Use the selection tool in combustion to just select the sabre itself - you will need a travelling selection for a frame sequence and just recolour the blade. It looks as if the rest of the frame is correct in the original shot.
