Not exactly. What he said is that he didn't want to give a straighforward answer because his plans may change in the short future, but his exact words were "The game is 98% complete (refering to the version number), but he has all the material he needs for a sequel". Later he went on to talk about all the new arcs and the plans he has for some characters, like Tiffany, Jared, Ella, Michael and more. There is no chance he can fit all these in the 2% left unless he changes the versioning system to 4 decimals.
There are many things that can happen
He may stop Superhuman for a while to get started with one of his other games, then return to Superhuman for the sequel.
He may stop developing the story further, do a full polish/rework certain parts, put it on Steam, and then start developing the sequel.
Or other interpretations that I can't think of at this point.
