Difference between point operator and full call number in Clojure

I am learning Clojure. However, I do not have a good understanding for language and philosophy.

But I want to be more familiar with the language. hence I started reading Clojure's basic API documentation and found some interesting things in the source code clojure.core/get.

(defn get
  "Returns the value mapped to key, not-found or nil if key not present."
  {:inline (fn  [m k & nf] `(. clojure.lang.RT (get ~m ~k ~@nf)))
   :inline-arities #{2 3}
   :added "1.0"}
  ([map key]
   (. clojure.lang.RT (get map key)))
  ([map key not-found]
   (. clojure.lang.RT (get map key not-found))))

To get a value with a given key, a function is used in the code clojurelang.RT/get. The code calls the dot operator - (. clojure.lang.RT (get map key)).

My question is why the author wrote (. clojure.lang.RT (get map key))instead (clojure.lang.RT/get map key).

Is there any technical difference? or any benefit?
