Oh, I see now. You're reading "Having IPv6 access is a necessary for accessing Google". What I meant was "If the presence of AAAA records means you can't access a site, then you can't access Google".
A user who only has IPv4 connectivity relies on their software recognizing this when accessing an IPv6 enabled site. Software's failure to do so is one of the main reasons for the slow rollout of IPv6.
