Auggie's are tipped incorrectly, his ears are VERY very thin and gentle. When he was younger they did stay correctly for a bit - I have photographic evidence, LOL - but then they went all hound ears on me. I don't care, I think it gives him some of his personality, but I do wish they were at least a bit more correct. Unfortunately I just don't think, structurally speaking, they would have done correctly. At least they aren't prick ears, for some reason I think he would look ridiculous like that, LOL.
Pepper's ears aren't my property so I can't say anything about those, LOL.
I'm hoping my next dog will have a better ear set. I'm going to make a much bigger effort to get them to set correctly, that's for sure. And YES people think it's sooooo mean to glue down a puppy's ears. Sigh. The worst part of it for Auggie was he had to stay still while I was gluing them. =P
To me it's part of the overall look of the breed... both of my sister's shelties have prick ears and their heads on the whole look different because of it. The ear shape does change the head shape, at least to me, and I definitely have a visual preference as far as head shape goes, so... yeah. It's all kind of one and the same about the stuff I like about how the breed looks.
