It's a pretty obscure in-game notification, given that the Active Help tip comes up the first time you complete any achievement, and chances are it's a long time later before you complete any that give a reward, so the part about Jonathas is useless when presented and hard to find when it actually becomes meaningful. (Really, a single sentence at the end of a help window that you'd seen once, probably months earlier in most cases... Who would remember it from that?)

I'm pretty sure most of us learned the answer from threads like this one rather than in-game from that Active Help tip. A few people randomly happened to talk to him when they were eligible to get items and then realized there had been achievements earlier that were supposed to give those. So they posted about it and it spread by word of mouth through the forums and other fan sites.
