Yes.

Ah, are you referring to the condition that the current column number be
greater than fill-column?  This condition is enforced by the default
value of normal-auto-fill-function when auto-fill-mode is enabled,
namely do-auto-fill.  A different auto-fill-function mightn't enforce
it.

In general, there are multiple conditions guarding calls to
auto-fill-function (see e.g. internal-auto-fill and
internal_self_insert), and I'm not sure the docstring of newline is the
right place to discuss these things.  How's the following clarification
for emacs-26 instead?
