Sounds to me like the person just wants others to agree that WN's program is much better than AS. I too am a 75k, and like many others I also book my tickets at the last minute (advance planning for me is 12 days, mostly it is 3-4 days out). I get upgraded quite often, but I also was able to select exit row seating. The only times I have purchased a ticket without a seat assignment is when I booked a ticket for the next day. Since I really needed to fly, I was happy to get a seat, and was happy with my middle seat in the back.
