Saying "anti-aliasing" is a reason to see NO aliasing is far more ignorant than anyone not knowing what anti-aliasing is. Almost every console 3D game exhibits a degree of aliasing, usually severe, whether or not anti-aliasing is used. There's even still aliasing in supersampled Dolphin games, in the surprisingly immaculate PT, it's not something you flip a switch and it's gone. Even with good AA certain shaders and effects exaggerate aliasing or are not covered by certain AA methods--for example DOF'd edges have about twice the aliasing as other edges in TLOU:R and Infamous Second Son.
The Order's solution is simply exceptionally good, just "anti aliasing" is not a proper way to describe why it actually appears to work so well.
