Which just goes to show how confused we can get when the pronouns aren't clear - because I read it the way you did, at first. But because the bit about the sleeping bag zipper was in the following paragraphs, I think I got the impression Heero's hands were still in his own sleeping bag or something - I dunno.

I didn't highlight the paragraph that way because that's what it *does* mean (I have no idea) but to illustrate how one uses name, pronoun, pronoun, name, pronoun pattern to clarify confusion between pronouns. Not because I knew which she actually meant.
