Why I'm against his statement about SG worldline being an anomaly, is because Beta future Okabe found out a way to create a cause that will lead the world to a different future than Alpha and Beta Attractor Fields but the resulting of that change will still be the same at the Turning Point so there is no convergence happening.

Okabe in 21/8/2010 traveled back in time to 28/7/2010 must save Kurisu and somehow destroy the time machine paper nakabachi will bring to russia, but he must deceive his past 28/7/2010 self to see Kurisu lying unconscious on a pool of blood and make his past self thinks that Kurisu died, and by doing so his experience from sending the very first D-Mail until the moment he entered Beta Worldline and then traveled back in time trying to save Kurisu won't be undone.

Okabe can't deny his past experience. If he tried to save Kurisu by different approach, that is where the convergence will happen. Because Okabe himself already saw Kurisu "died", no matter what he did, convergence will make his past self saw her "dead". Making a Casual Loop, in which 21/8/2010-Okabe makes 28/7/2010-Okabe experience the same event like he already had, while preventing direct Grandfather Paradox in which Okabe denies what he already saw in 28/7/2010 and erasing the cause of his whole experience that makes him wanted to save Kurisu so badly.

With that in mind, the result, Okabe in 28/7/2010 saw Kurisu unconscious on a pool of blood, still the same, but the effect it took creates a different future than Alpha worldlines and Beta worldlines, a worldline not within range of both Attractor Fields.
