Thanks for asking, claudiagarin!. The bulk of the last paragraph is dedicated to answering the question posed by the author in the second sentence:
Do our findings therefore call the concept of the multiverse into question?
The answer, according to the author, is no, they do not, and she gives two reasons why not. That is discussion what the research does, or in this case does not, imply. It's an argument about what the research doesn't require, and "X does not imply Y" is still a discussion of the implications of X, even if the result is "no such implications."
