You should read this:
http://www.exim.org/exim-html-4.66/doc/html/spec_html/ch40.html#SECTaddressverification
It's not so vague at all ("The first stage of address verification,
which always happens, is to run the address through the routers, in
verify mode.") It tests if routing can succeed, so if the domain doesn't
even exist, it won't be accepted for example.
