It looks perfectly fine to me. Both nameservers hosting your domain
have both A records. I'm not sure what kind of "flexibility" you're
talking about, since there's nothing unusual about what you're doing.
These are just ordinary hostnames in a domain -- that's what nameservers
deal with all the time.
