Learning is very much a multi-sensory process. The act of writing is part of the learning - the two-dimensional shapes your fingers trace actually help cement the memory in your brain. (And no, simply clacking away on the keyboard is not the same.) As these authors [1] say: "the additional context provided by the complex task of writing results in better memory."
The study you've referenced is invalid for this particular discussion (but it's an interesting read and thank you for posting it). The study is focused on memorizing words, with this limitation being clearly stated in the study: "Future research is necessary to investigate the effect typing has on remember more complex stimuli, for example, phrases rather than just words."
It's also notable that the participants are 72% percent female (females as a population are better at writing than males [1]), and that 72% of participants admit that they prefer pen and paper.
Having said that, I agree with the study in that the kinesthetic aspect of writing will generally lead to better retention of words - I believe this is well established.
