do even googles ips confirm to this standard?

As I previously stated the reverse pointer does not have to match your domain. 

Suppose you ran a hosting company called host.com. Suppose you had clients
client1.com and client2.com. This requires virtual mailboxes. That is one
domain, host.com provides email services for client1.com and client2.com. Most
servers would just have a reverse pointer to host.com.
