That is a weird way to turn on auto-fill mode and I would not be
confident it is setting up the mode correctly. See the Emacs manual for
the official way to do this using mode hooks.

I don't think you want to turn on auto-fill mode in ALL modes. Some
modes, you really don't want Emacs to modify buffer contents by filling.
Typically, you only want this when your dealing with text (so text-mode
hook is a popular choice for adding auto-fill-mode).

I would also be wary of emacswiki advice. While there is some good
advice there, there is some which is not very good and lots which is
outdated/obsolete. This is the downside of wikis. Always try to verify
the advice using the manual corresponding to your Emacs version.
