I don't see the parallel as intended to put Napoleon down, but instead to attribute the same force of personality to Hitler. As someone who never met either man (perhaps that's obvious :), I'm not sure the connection works with me.
"I saw the Emperor -this soul of the world- go out from the city to survey his reign; it is a truly wonderful sensation to see such an individual, who, concentrating on one point while seated on a horse, stretches over the world and dominates it."
Similarly, Hitler saw himself as being the concrete expression of the soul of the German people. He may not have been aware of the quote, but the ideas it expressed were strong themes in the German romantic movement.
"As far as the philosophy of history is concerned, what is the first trait of the Hegelian vision of the Napoleonic hero ? A famous passage is often quoted. It is an extract from the letter Hegel addressed from Iena to his friend Niethammer, October 13th, 1806, when he had just finished writing The Phenomenology of Mind : " I saw the Emperor -this soul of the world- go out from the city to survey his reign; it is a truly wonderful sensation to see such an individual, who, concentrating on one point while seated on a horse, stretches over the world and dominates it. " (Correspondance, T. I, p.114)."
"Napoleon soul of the world" makes a pretty good search phrase[2].
