(with-open [rdr (reader file)] ...........) So the vector you referred to is for binding and in imperative that means assigning rdr to function (reader file). So now it is pretty obvious that what you need is the variable, rdr, (in side the scope) and that's why clojure takes only the first element of the vector.I guess that's logical.
