Did anyone else notice this (Easter Egg) in Bioshock Infinite?

At least in this one they didn't completely shove it in your face.

Just gently shoved it in your face I suppose.

I remember rolling my eyes in Human Revolution when David Sarif is all, "The code to that door over there is 0451. Did you get that? It's 0451. Once again, in case any of you fans were worried that this isn't a real Dues Ex game, THE CODE IS ZERO-FOUR-FIVE-ONE!"

... He only really does that if stick around his office and don't go to the elevator.
