What is the meaning of Sambhavami Yuge Yuge?

To have just the meaning of "sambhavami yuge yuge", it is "i will come back millennium after millennium." But that is only a part of the complete verse below... "Yada yada hi dharmasya glanir bhavati Bharata; Abhyutthanam adharmasya tadatmanam srijamyaham. Paritranaya sadhunam vinasaya cha dushkritam; Dharma-samthapanarthaya sambhavami yuge yuge." which means... "Whenever the balance of the universe is disturbed by external interference from any of its parts, then I reveal Myself as the Power of eternal balancing. For the protection of those who are in harmony, and the rectification of everything disharmonious, I incarnate Myself at every juncture of time."
