Oh, I see.  Well spotted.  I think the simplest solution here is to
start off the nnimap sequence at a higher number so that these things
don't get in each others way.

Does the following patch (pushed to Emacs master now) fix the problem
for you?

diff --git a/lisp/gnus/nnimap.el b/lisp/gnus/nnimap.el
