the Brep with multiple Faces is converted / casted to a Surface.
(and maybe this conversion is just using the first Face/Surface of the Brep)

add 2 parameters to see the misstake.
(see the surface and Brep parameter i added)

hope this helps for debugging.

how to solve it ? use extrusions that run through the object and use those as cutters with Split Brep Multiple.

EDIT:
the function you where after is available in rhinocommon
brep.Split(…)

you can access it with a scripting component:

You may give it a try with Split Brep Multiple, and fyi.
