"Ubisoft makes use of a "temporal filtering" feature that has a pretty interesting impact on the game.
Essentially, this feature renders the game with half the number of pixels on each axis with an ordered grid MSAA pattern before reconstructing the image to match the final output. This is then coupled with a post-process temporal anti-aliasing solution to minimize artefacts in motion. So, at 1080p, we're technically seeing 960x540 with 2x MSAA."
Edit: The article does not specify the Xbox One's resolution beyond an end result of 900p, but if we apply the same formula, (a halving of each axis) we're looking at 800x450 with x2 MSAA.
