> indicating she no longer thinks her accusations hold any water

This is the only thing in your summary I disagree with. From my reading of the issue and knowledge from following it I think Leah still very much believes in her accusations. She just has realized that at this point even if she's right nothing positive is going to happen and realizes she handled the whole situation awfully so is apologizing for that.

I didn't read anything that suggested that she didn't think the accusations were true anymore.
