No, which is my point. Allow myself to quote… myself:
Well, we can also look at precedent. Article 5 was applied only once in NATO’s history, despite multiple other occasions where NATO could have done so.
As for your other line of thought:
in the scope of the treaty (which, yes, must actually be triggered), a response from all member states is mandatory.
This is also demonstrably incorrect. If we look at the single time Article 5 was triggered, 9/11, the response was not all-in. The largest-scale combined effort I think was patrols in the Mediterranean.
