Beating Ortiz and Fury consecutively:ATG HW acheivement

I've noticed people are conflating the (hypothetical) Achievement of beating two top 5 hw's consecutively, one of whom is often considered the lineal champ, with PERSONALLY being an ATG. I'm not saying Wilder would himself be an ATG upon beating Fury. Just that that specific achievement would be an ATG achievement. Tommy burns had an ATG achievement in getting 11 consecutive hw title defenses, and Spinks had an ATG acheivement in ending alis lobgest title reighn, but neither is really an ATG himself, as examples.
