What I want to know is that whether `fromnode` is already assigned to all user nodes before the execution of `~connect @filter(not uid(fromnode)){`, or  
it works node by node, that is, the `~connect @filter(not uid(fromnode)){` inside user node A only removes user node A, and `~connect @filter(not uid(fromnode)){` inside user node B only removes user node B
