I used that offer in my Amex Offers a few days after the public business applications went "once per lifetime." I had already had the BGR and closed it ~18 months prior, and I got the points. Take heed, though, I saw the same offer (again!) in my Offers section a week or two ago and now it's gone
It could have disappeared since I just got the same offer/card, but that didn't stop them from putting it there for a few days...
