He's oversimplifying it. It's more that Alan, while trapped, keyed into something which was already there (the FBC) and is trying to write them into helping him.
But consider it a be a roswell that ends well. The entire reason he keyed in wasn't for help. His audio logs stated that he didn't know about the his. He is now essentially a narrator of reality. Is he typing things in because of prophecy or because what he types he manifest. It does state that he created the hiss in one form of another. This combined with his presence in Quantum Break allows for more realities to be broken as now his creations and power can now express themselves across different dimensions/timelines. In fact if you replay Allen wake and watch those tv shows, you will see that jesse faden was a character he created yers ago when he was a tv writer. Its either heavy handed forshadowing of Control or that when the events of QB altered reality that he created the oldest house.
That being said those dev tweets and in game logs seriously make it seem they are jumping through monster hoops to keep their games into one universe. Speaking of this has Matt Patt did a dissection of this yet didnt see one but you know how youtubers get with special guests.
