From a New York Times story by Peter Baker headlined “Biden Veers Off Script on Taiwan. It’s Not the First Time.”:

SEOUL — Maybe President Biden isn’t speaking off script after all. Maybe he just doesn’t think much of the script.

Offhand remarks that vary from the official talking points have become a feature, not a bug, of the Biden presidency, as he demonstrated again on Monday when he dispensed with decades of “strategic ambiguity” and indicated that he would militarily defend Taiwan against attack by China.
