Man, is every sibling relationship in Naruto this dramatically weird. Lol.

To be honest, I don't think so, people in the same villages probably address people with respective and friendly status and all such as that. Like Obito calling the old people, grandpa, grandma(I think), Kid Sasuke calling the old man and old woman in his clan, as Uncle and Aunt. And Konohamaru calling Naruto big bro, or something. There are many other instances. It's probably just how she called him before he turned evil, and still calls him by that, because of habit or just a kind of respect to their old memories, I think. But it can also be as the case you've said.
