It was a response to your response of her response to Joseph’s post (but I think you hadn’t realized that she was responding to Joseph initially), so it was in essence a response to Joseph’s post (although I think you didn’t realize that).

Agreed. I was just explaining what she meant; I was not saying that I agreed with her.
