Thanks for referring to the documentation. It already explains this in
(info "(elisp) Defining Minor Modes")
-- Macro: define-globalized-minor-mode global-mode mode turn-on
keyword-args... body...
...
Globally enabling the mode also affects buffers subsequently
created by visiting files, and buffers that use a major mode other
than Fundamental mode; but it does not detect the creation of a new
buffer in Fundamental mode.
