Styles of this sort only apply to completion (as might be obvious from
the word "completion" in the context) and only because there is a layer
of user-defined functions implementing most of the completion system.
There are no built-in shell operations that use zstyles values directly.

This might mostly do what you want:

    autoload -Uz add-zsh-hook

    no-local-autocd() {
      set -- "${(z)2}"
      [[ $1 = */* ]] || unsetopt autocd
    }

    reset-autocd {
      setopt autocd
    }

    add-zsh-hook preexec no-local-autocd
    add-zsh-hook precmd reset-autocd

I say "mostly" because if you do something like

    % echo foo ; /usr/bin

the autocd to /usr/bin won't happen because "echo" caused the option to
be turned off.

You can do a similar thing by overloading the accept-line ZLE widget, or
in more detail by using a DEBUG trap with the DEBUG_BEFORE_CMD option set,
but either of those has its own problems.
