Models are downloaded only once and then cached, and not repeatedly like the OP mentioned. Source: Me. I've developed it. If you disagree, are seeing a different behavior or have further questions, please reach out in the repo: github.com/mozilla/firefox-translations/
We retrain models as we get new datasets and only if they improve, which is not common. So far we haven't updated any model. When it's time, then yes, they will be updated, but it's definitely not a frequent process.
