I'm looking at the article, and I'm seeing some broad generalities that still require a "helpful monster" scenario. For example, "b. The type III export system is converted to a type III secretion system (T3SS) by addition of outer membrane pore proteins (secretin and secretin chaperone) from the type II secretion system." That still requires a multistep "leap" from the previous stage, as do several other steps.

You're referring to the part that speculates how a system considered "irreducibly complex" could be produced naturally. The speculation may or not accurate reflect the true development of the system.

I was referring to point #2 where the bacterial flagellum is shown to not be irreducibly complex. As others have since posted, systems that are considered irreducibly complex might not be.
