Precisely.

They currently have control of your reverse records. You want to have
control, because they aren't doing things right. So you want them to
delegate authority for your reverse records to your servers.
Without that delegation, it won't matter what reverse zone file you
have on your servers, because nobody in the outside world will ever
see it.
