No, it is as specified, and indeed is also explained in FAQ0809.

Precisely. That's what the FAQ - and my book (page 429) - say.
Why does it do it like this? Answer: because of the possibility of
negative items.
Consider:
something = ! *.a.b : 10.9.8.0/24
If Exim cannot find the host name, it cannot tell whether the host
matches *.a.b. So it cannot proceed. Order matters.
