Every advert thus far has been a reference to something in Wanda and/or Vision's past. I see no reason why that would change now.
Also, it's a direct allegory for what vision is doing in this and the previous episode: J.A.R.V.I.S. was "dead", yet continued to exist with no memory, only an impulse to protect the people of the world from a destructive force. And the place he was recovered by Stark was at the Nexus hub.
Weighing that against a random, meaningless concept that has never even been mentioned anywhere *ever*? Yeah...no.
