No, that can't be, he would have said "IP addresses".

The DNS is already a layer of indirection so in most cases this makes things harder first (having to remember which 
address is on which host) so they may be easier later (not touching the DNS when services go to a new box). In my 
opinion, this isn't a good tradeoff most of the time. Only if you want/need addresses to be a particular way (like 
short for DNS servers) that's helpful.

I was reluctant to do stateless autoconfig for servers at first but it's really rock solid, as long as you're 
reasonably sure no rogue router advertisements will show up on the subnet in question there's no reason to avoid it.
