I am certain the author of that piece did not mean it that way. I do not think that he was referring to the game helping him aim, rather that with the motionplus and all the upgrades to the game that where he was pointing was where his bullets went.
I always thought that Conduit was pretty fine as it was when it came to point and shooting, but maybe just maybe HVS found a way to make the sensor bar more sensitive to your every gesture allowing you to pull off better shots based on your own skill.
So maybe there will be people complaining about the motionplus helping too much maybe not. As far as I know the motionplus is mainly there for the off-the-screen stuff like knowing where your aiming if you do fire off thee screen.
