Yup that's how these exchanges work - you're only guaranteed one match out if your recipients request - but you can choose to write any of them - the prompts don't go to multiple people. E.g for parallels 2012 - my recipient had four requests in four fandoms. I only matched for one fandom (oresama sensei) but I ended up writing for another fandom Kimi to Boku as I thought I could do a better job - it didn't matter which request as long as I could fill one. (When there's so many people it's difficult to guarantee perfect matches so idea is to make sure everyone get's at least one option.)

So yes you're assignee will get all three prompts - but they only have to write one of them.



Although, another thing to keep in mind with some of these exchanges the prompts become public in the last week (to encourage people who have finished to find things to treat if they want) - that's why I put all my general stuff in my letter and link the letter for each prompt rather than repeat myself.) as treaters might not see all of the prompts which get separated. (There's no guarantee that someone will treat, but making it easier certainly won't hurt your chances. :3) I don't know if that's what Kimmie is planning though.

(You don't have to write a letter and you can just say see my letter in the ao3 requests, this is just what I prefer and why.)
