The article provides additional inferential evidence to what quantum mechanics already has provided. The multiverse is the best candidate for a theory of everything, and this analysis of the CMB merely confirms it.
But you are making it sound like its a hard fact.
They think this makes sense. They assume it makes sense based on their findings.
This can also be wrong.
There can be another evidence they missed, or some other theory in the making, or they thought it makes sense and so their assumptions of their observations where leading to it instead of the other way around.
They have still a very long way to go in order make this theory more substantial. In the articles liked earlier, there are several holes in their theory which they still do not understand, but filled with things they assume are right, and still need to prove them.
