Method parameter copied (not moved)

Question

I have the following code:

// header
    void Method1(const bool& b, std::vector<int>&& v);
    bool Method2();

bool CMyClass::Method1()
{
    std::vector<int> v{ 1, 2, 3 };
    TRACE("%d\n", v.size());
    Method2(true, std::move(v));
    TRACE("%d\n", v.size());
    return true;
}

void CMyClass::Method2(const bool& b, std::vector<int>&& v)
{
    TRACE("%d\n", v.size());
}

Outcome:

3

3

3

Seems v is copied, if so, why not moved?
