You do need to start the reservation process fresh again to trigger that offer. However, you may book the second ticket first, and then cancel the first one (this should protect you). The system does not do real-time checks for duplicate bookings; however, if you were to let them sit for hours you might have problems.
You could also call and ask about the upsell, but they are usually web-only offers. You are also very likely to see the same (or similar) offer during check-in if any F seats remain at that time.
