To everyone asking about this version, I am thinking that she wanted the song to be about love and only that. This version seems to show love and sorrow all wrapped up.
As you might recall, in the original version he is an angel who is not really there. In some scenes she is reliving memories and others he is simply watching over her as her halo or protector.
In this version we get to see why and how he died and how it makes her feel.
