No, itʼs not required there, you are free to enable ‘my-precious-keys-map’ unconditionally as well:
(add-to-list 'emulation-mode-map-alists
(list (cons t my-precious-keys-map)))
if you feel that you will never need to suspend it.

There is no any trickery, just a hardcoded priority order in Emacs itself: global map is overridden by major mode map, which in turn is overridden by minor mode maps, which can be overridden by emulation mode maps.
That is, using a minor mode map would suffice in your specific case — about M-o in diff-mode. But so would a mere:
(with-eval-after-load 'diff-mode
(define-key diff-mode-map
(kbd "M-o") nil)) ; also on RET, o, C-c C-c, which is more than enough

| Optional INIT-VALUE is the initial value of the mode’s variable.
