I say it's a rather appropriate ending to Deadwing, and Half Light is like an alternate ending. As for the meaning of it, I'd say it's that the girl is, in fact, dead. In this one, she's thinking about how they "Touched" each other when they were together, where as Half Light is her apologizing to the guy.

I interpreted Half Light as him "forgiving" her after her death, or forgiving himself for his reactive emotional lashing-out at her after she dies -- obviously to himself, but he still carries the guilt. The lyrics simply add a spiritual sense, that she had not yet moved on in order to help guide him in to better times. It kind of sums-up her entire part of their relationship: to show him the love he never had and help him grow strong.
