In the video, they explain it as embracing the conception of the letters as being 3d objects. The added weight in the lower parts would intuitively anchor that letter in that orientation. Perhaps a 'j' should be tilted due to its asymmetry.
As for my $.02, I think the mix-ups often occur in real-time due to proximity. Making the symbols distinct would perhaps lessen the likelihood that the brain will try to identify those conceptual objects as a unity when they are near one another.
