Grasshopper point select domain

hi, I want to select specific points with the graph mapper

I want to use a subdomain, but it seems the domain is not applicable.
What do you think is the problem?

It seems you have a lot of duplicate points, is that wanted? I suppose not.
See pic, the selected “Branch” component is the same as in your picture:
duplicates
Probably something gone wrong while using paths… and this is going against you understanding what is going on.
(try to bake that selected object, and see in rhino where and how many points duplicates there are)

Can you explain better what you want to achieve? I didn’t understand…
