Tools.namespace reload does not work? or is it just me using it wrong?

From the documentation it says that

The refresh function will scan all the directories on the classpath for Clojure source files, read their ns declarations, build a graph of their dependencies, and load them in dependency order.

(refresh) never reloads anything for me. Am I using it wrong?

For repro I have two files:
a.clj:

(ns refreshdoesntwork.a)

(defn get-a-map []
  {:a "a"
   :b "q"}) ; change q to b, just save file, 
            ; then I expected (refresh) in namespace b to react.

b.clj:

(ns refreshdoesntwork.b
  (:require [clojure.tools.namespace.repl :refer [refresh]]
            [refreshdoesntwork.a :refer [get-a-map]]))

(refresh)

(println (get-a-map))

Actual behavior:
file b, get output {:a a, :b q}
in file a, change :b "q" to :b "b" save the file
run (reload) in b
run the print funtion in b
then the problem, I get the output {:a a, :b q}
Nothing is updated.
