Rendering Translucent Material Explaination

I encountered a problem with using translucent materials.

I would like to show a plane and a sphere within a coordinate system. The plane is cutting through the sphere, but though both are translucent, it looks like the sphere is before the plane, not intersecting it.

It seems like it is not a bug, but more a limitation of how the rendering in Unreal works. I found a YouTube [Video][2], where a guy is explaining why the problem occours.

I’m wring my bachelor thesis about a project in Unreal, where I encountered that problem and I’d like to describe why that problem occours, but of cause I cannt use a YouTube video a source for my explanation. So where do I find a proper source for information on how Unreal does the rendering from translucent materials?

And other question, am I correct, that there is no way archiving my goal in Unreal? (I tried that dithering its not working how I like to.)
I want to have multiple translucent objects intersecting each other.
Here is my material setup:

So can you give eather a way how I can archieve my goal, or a link to a description of how the rendering works and why its limited in the lanslucenticy.

Thanks for your help!
