Not sure exactly what your aim is as ultimately the geometry is copied to points. Checked the attached scene vop sop manipulating points via a foo attribute

Well as FOO is a vector with x y z all you need is to add the Y component to the current P , to peel off use a vector to float vop coming from the aa noise vop

Well is a clear way of saying the data can leave at this point. As we might want the result to drive somewhere else in the network and others opening your scene can see that.
