I don't feel that the addition of saying that the judge can make the conditions explicit is necessarily in concert with the previous statement in that clause, which says that they're not to be using it for any reason whatsoever, except when a judge says they can.
The previous clause, which simply said that they're not to use it for the purposes of communicating with children, seems to me to be far more precise and to the point as to the type of behaviour we want to be preventing.
