I'm pretty sure we've already seen cases that prove that it doesn't, perhaps not enough to write a blog post about, but they are definitely out there (iOS 7's dramatic increase in the use of motion comes immediately to mind). I think it's a dangerous sentiment to promote in such a generalized sense and designers/developers need to be very cognizant of the value any animation provides to the UX. It's far too easy to justify the abuse/overuse of motion/animation, making any animation noticeable to "delight"/"tell a story" which contradicts any functional reason for implementing it.
I found the post overall to be pretty superficial. There was only one paragraph spent on describing the function/purpose of "motion design" and it placed far more emphasis on it's more marketable aspects than on it's utility to "educate your users about how to interact with particular elements".
"Motion design" is just one UI tool and one that really didn't need to be pulled out and promoted in this way IMHO as it's always been an essential tool in great software when used properly. I think it would have been great if it wasn't an "implicit announcement" but explored in detail what good "motion design" entails. It's easy to get carried away with it, and introducing motion with appropriate intent can be what makes an otherwise good application into a great one, but let's not pretend it's magic dust that can turn cole to diamonds.
