Will they know if I comment?

I answered a question and was chosen as best answer. After choosing my answer the questioner asked me about something I had referred to in my answer. This person doesn't allow email and, since the question is now resolved, I can't add to my answer to explain it to her. I told her she could email me for an explanation using the 'comment' section under the question, but I don't know if she will see it.

Does the questioner get notified if someone makes a comment on their question once it is resolved? Otherwise I doubt anyone would ever look back for comments.
