Both the Schrodinger equation and inflationary cosmology predict alternate worlds filled with alternate yous. MWI refers to the former. The author of this piece is talking about the later.

If anyone is looking for a simple introduction to the Everett interpretation I'll point you to this short lecture by James Ladyman: https://www.youtube.com/watch?v=cgXVEeL9tzM

My understanding was that some theories of inflation require multiverses to exist. I have never heard that the Schrodinger equation nor inflationary cosmology themselves predict alternate worlds. Some theories require them (to get the math to fit), but there are definitely alternatives.
