Your syntax only selects residues, so this is to be expected.  Something more 
along the lines of:

lipids = same residue as (name P8 and z >= 3.2);
lipidC = name C* and lipids;
lipidC;

should probably be more along the lines of what you want.  I haven't tested 
that, but it's probably pretty close.
