I've been thinking about this and am even more confused.

Q1.  Does the domain match do a DNS lookup to get the matching IP 
address each time it is asked to compare against the sender's IP address?

Q2.  I looked at the code in acl.c and it appears that the match routine 
for "domain" is acl_domain_cmp which compares two strings, 
back-to-front.  I don't see any DNS lookup there.  You certainly know 
the code much, much better than I do, so what am I missing?
