What does Twin Eidolon do actually?

[Barachiel Shina]

I am confused by the Synthesis capstone ability. It looks like it does everything that being Fused already gives you, so what's the point of it really?

Is it really only beneficial when you do Split Form? Such as splitting you and Eidolon apart, and then using Twin Eidolon to gain the same benefits?

What's the difference between it and Fused Eidolon and what are the benefits/cons?

The primary benefit is that twin eidolon doesn't involve fusing with your eidolon--you take on the physical shape of your eidolon, and your actual eidolon remains a separate creature. Hence "twin eidolon". That's pretty strong.
