Why was the name of Pontius Pilate included in the Niceno-Constantinopolitan Creed?

Why was the name of Pontius Pilate included in the Niceno-Constantinopolitan Creed? Why was it important to mention his name in the creed? If only because of historicity, then wouldn't just a mention "governor of Judaea" have sufficed? Or at the very least the name of the Caesar would have served better then (just like it was a custom in many historical writings, Gospels included): "governor of Judaea under Emperor Tiberius". Yet we see exactly Pontius Pilate's name mentioned. Why is it so? It is especially interesting a question when you consider the other names mentioned in the creed, that is, only two names: "Jesus Christ" and "Mary"! Nicene creed that preceded the Niceno-Constantinopolitan did not include "Pontius Pilate", which means that there must have been a valid reason for the inclusion. Besides, the reason must be stated in the documents of the Second Council. However, I haven't met the stated reason yet. The wikipage on Niceno-Constantinopolitan Creed doesn't have an answer to this question.
