At the very top of _ssh_hosts is:

  # If users-hosts matches, we shouldn't complete anything else.

The users-hosts completion looks at /etc/hosts and ~/.ssh/known_hosts,
so hosts from your ~/.ssh/config are only completed when no possible
matches are found in either of those other places.

(Or at least I think that's what's going on, because the very next
thing in _ssh_hosts is to examine ~/.ssh/config (or the config file
name following the -F option).)

The explanation is here:

It seems a bit odd that this kicks in when there is no user-name part
in the word being completed.
