The Ascendant and the sun don’t mean the same thing, so I wouldn’t necessarily say that it’s odd.

And I guess so. The beginnings of signs in each of the Mansions is supposed to represent a “coming to terms” in the last few degrees of the first sign, plus a “newness” in the first few degrees of the second. The growth of that first sign would show the beginning traits (or stereotypes, which I hate referring to signs like that btw) of a sign.
