For the learning proces

I am nothing using grasshopper for a very long time and I need your help with a simple question. The part of the script that is seen in the picture. I am sure this can be made easier. There are six breps which are cut by the other breps. How can I solve this without the wire mess? Thanks for your time!

This might help:

Flatten your initial pool of breps.
Graft Shape input.
Leave Cutters input flattened.
