Yes, there is a redefinition. The context of Alpha Wolf was based on the notion of a dominance hierarchy, which does occur when unrelated wolves are put together in a confined space. In the wild though, they function more like a family, with no acts of dominance. The breeding pair still lead the pack, but not through dominance.
