I imagine the editor did "care to check", and found that you were inquiring less than a month after you last received a status update. Asking you to wait the full calendar month was quite correct.
We get lots of requests for status. In order to answer them all, we have to limit how often they may be asked. And if we relax the limit for somebody, then everybody will use the relaxed limit and somebody else will try to push it a little further. That's why we strongly discourage attempts to inquire about status any more frequently than once per calendar month.
