why do Vagrant docs suggest using public IP address 33.33.33.10 for local VMs?

private-ip

I'm following a tutorial to set up vagrant (a tool to build and configure portable virtual machine images), and it seems that vagrant documentation suggests using IPv4 address 33.33.33.10 to configure a new box.

That is a publicly routed IP adress, so I'm a bit confused why using this address is suggested. Since I don't own this network, I should not use an address from the 33.33.33.10/8 range. Am I correct in thinking that I should only use either a public address from a network I own, or an address from one of the private ranges as defined in RFC 1918? If so, why does Vagrant documentation suggest otherwise?
