Xavier claims to have understood something about The Beyonder back during Secret Wars. He claims to have touched his mind and become enveloped by it and before he was overwhelmed he felt that it had something of the Inhuman about it and something of the Mutant about it.
He claimed it was faking being from 'Beyond'. He posited that an Inhuman with a mutant gene may have become The Beyonder. None of that is set in stone. Xavier could have been entirely wrong and misguided. Even the story casts doubt on his version of events, not least Xavier is openly struggling to put the idea in words. The idea may just be his personal interpretation of something else. An analogy if you will. The notion also has some doubt cast upon it when Black Bolt has no memory of this character.
Look deeper and it is probable that Bendis and Reed were exploring briefly the theme of The Beyonder, and what exactly it means to Marvel continuity. There is an element of 'the writer within the work' going on, which was so prevalent in Secret Wars II, and we even get a telling line in the comic as the Illuminati leave:
"There are those who believe that we are just passing through time and space that was created by others for others".
That line was spoken off-panel, apparently by Dr Strange, but because he is not shown and because the bubble is pointing back at us, it also has a subtle meta-text feel about it, as if the writers are using the character who has the most experience of the transcendental, to speak their own words, and tell the Illuminati that they are just comic book characters.
The story is more about the hubris of The Illuminati, making pronouncements upon the uncertain and often nonsensical world around them, than it is about The Beyonder. Notably the Illuminati are shown images of their own ideals and wishes and in the end believe they have solved the problem when The Beyonder actually carries on with little regard for them. It leaves the distinct possibility that Xavier was just projecting that The Beyonder was something that he and Black Bolt could easily deal with, when in fact it was something entirely outside of their understanding or control.
To put that 'simply'. Illuminati #3 is a meta-textual examination of meta-text itself, as seen through the eyes of the characters that are impacted by its out-workings.
