I think it's because in a normal-BMI woman, some of the breast is fat, but most of it is breast tissue. In an obeast, there's still some breast tissue, but there's a lot more fat in comparison to a normal-BMI woman. And fat tissue, as we see here all the time, is lumpy, bumpy, and doesn't really follow any sort of shape. You can have 2 obeasts who weigh the same who look completely different because of their fat distribution. I think it's the same with breasts. Also I thought LaSenza only went up to a 38DD? Aren't most obeasts too fat to fit into those bras?
