Right, as long as it was a green sticker day (and not green baby based on the previous days) then the act of intercourse would be infertile as long as it was right after your last reading of the day. And that is because the sperm die very quickly without fertile cervical mucus.

I hope you're working with a Creighton teacher - it's really the only way to get all the nuances down. If you don't have a local teacher, it can be taught via telephone or Skype. Good luck with it
