>> There are circumstances where a subset of the Internet's hosts may be reachable. For example, you may be able to reach link-local names without a broader Internet connection. Or you may be able to reach a host behind a VPN only when the VPN is active. (I don't know what Reachability actually does in these cases, but it's the sort of thing that the API was designed to handle.)

The docs say that it does not ping the host.
However, if you pass the host to the method, if you get a "maybe, try now" you can try the host in one shot in that method.
