I don’t understand why you think it’s wrong as it is. I think it’s fine (well, it’s my text, actually, so of course I do) and don’t see the problem. While your suggestions are also OK, I don’t think any is better.

The reason is that the client will be building a data structure of mailboxes, and it’s possible that clients won’t be able to handle a MYRIGHTS response when they have not built the mailbox entry from the corresponding LIST response. Another way to handle this would be to say that clients MUST be able to do that, it’s very unlikely that a server implementation would want to send them in the other order anyway, so it’s easier to set the restriction there.
