When I learned that Augustus was a title shared by all emperors I thought Romulus Augustus was called so just because of that which ruined for me the poetry of the last roman emperor in the west (Julius Nepos? Who is that?) having both the name of the founder of the city and the founder of the empire because so if it was common to all emperors then it wasn't so special.
But years later I learned he for some reason actually had took Augustus as a proper name (which meant that Augustus occured twice in his full regnal name) and so him being the last emperor in the west seemed even more poetic than I thought initially.
