If the parents have cache_dir null, those parents would simply be relaying the requests to the origin servers. They do not add any value - the child cache(s) can simply send the requests direct. If fact, you are adding overheads, the same 1 single request has to go through the child and then the parent, ie 2 separate processes to process the same 1 request. With SMP, if you have 2 processes, you can process 2 separate requests simultaneously. As usual, corrections welcome.
