partial returns a closure, closing over a at the time b is defined.

I'm reading Clojure Programming from O'Reilly.
(defn a [b] (+ 5 b))
;= #'user/a
(def b (partial a 5))
;= #'user/b
(b)
;= 10
(defn a [b] (+ 10 b))
;= #'user/a
(b)
;= 10
Redefining a has no effect. But,
(defn foo [] 1)
;= #'user/foo
(defn bar [] (foo))
;= #'user/bar
(bar)
;= 1
(defn foo [] 2)
;= #
