No, it sets the object name and default value. "If the new value is not a Stem object, a new Stem object is created and assigned to the stem variable, replacing the Stem object currently associated with the stem variable. The new value assigned to the stem variable is given to the new Stem object as a default value. Following the assignment, a reference to any compound symbol with that stem variable returns the new value until another value is assigned to the stem, the Stem object, or the individual compound variable." -- Shmuel (Seymour J.)
