Multipass SSS and Transmission

[rleuchovius]

I have a composition in After effects with these layers:

Emit (add)
Refraction (add)
Reflection (add
Dif

This setup works perfect, no difference between rgb and multipass comp.
However, if i add an sss material and use this composition:

SSS (add)
Transmission (add)
Emit (add)
Refraction (add)
Reflection (add
Dif

The composition is similar, but not exactly like the RGB.
Any thoughts on why?

I use srgb and linearize working space in After Effects.
32 Bit composition, all renders in 32 bit.
