Culling within a tree

Hello, 

(Attatched is photo)

I would like to cull each list inside the branches of the tree with respect to the boolean list of the previous branches but that are previously culled.

For example

in {0;0;2} i need it to have only indices 0,1,2 and until one of the next branches cull any of those indices. until for example in {0;0;5} it should have only index 0,1

Hope someone can help

Thanx,
