Actually he also said (in the link):

“The background was that President Putin declared in the autumn of 2021, and actually sent a draft treaty that they wanted NATO to sign, to promise no more NATO enlargement. That was what he sent us. And was a pre-condition for not invade Ukraine. Of course we didn’t sign that.”

It’s kinda like when they called it world war 1 and 2 - it didn’t actually include the entire world, but it did include so many countries that people considered it to be the world. The amount of people that could die or be affected by global warming could kill billions. Billions.
