What he means by messy construction is...
Making a web request, a server needs the IP address for the name.
CNAMEs forward the request to another name, requiring another DNS
lookup, in this case yet another name, requiring a third DNS lookup.
Use of A records instead of CNAME aliases for names keeps DNS traffic
down and returns IP addresses quicker.
