What profit of universal reference usage in range based loop?

Many times I saw code like this:

template<typename Collection>
void Foo(Collection&& c)
{
    for (auto&& i : std::forward<Collection>(c))
    // do something with i
}

For all STL containers (except vector) 'i' has type of lvalue reference. Is any practical sense to type 'auto&&' in this case?
