Could it have some benefits? Sure. Maybe you enjoy the movement of your fingers. Maybe it slows your brain down to the point where you linger on each individual word enough to see new things click.

Are these benefits enough to make it the best thing in terms of ROI? I would suspect only rarely.

- If you're not yet at the point where you can understand what you're typing, you are probably served better by more traditional language learning activities. - If you do understand it perfectly you're probably at an advanced enough level that just reading it at your normal reading speed, or writing your own stuff and then having a native speaker is a better form of practice. - If you can understand it with effort but not at a comfortable reading speed yet - you're probably best served by throwing the individual sentences along with machine translations into a spaced repetition system like Anki. Then you can see the same sentence multiple times over the course of a few days and deepen your understanding a little more each time.
