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.
