Yes, I was not clear on that, thanks for your feedback I amended the text
in the Tor Relay Guide aiming to clarify this.
here is the diff (which includes also other changes)
the most relevant change with regards to your comment is:
was: "Don't use any of the big DNS resolvers to avoid centralization"
is: "Don't use any of the big DNS resolvers as your primary or fallback DNS resolver to avoid centralization"
"if you want to add a second DNS resolver as a fallback to your /etc/resolv.conf configuration, try to choose a resolver within your autonomous system and make sure it is not your first entry in that file (the first entry should be your local resolver)"
