Moving lvalue reference into member variable

Assume you're having this simple class:

class GenericClass {
public:
    GenericClass(std::unique_ptr<uint8_t[]>& lref) {
    this->var = std::move(lref);
}

private:
    std::unique_ptr<uint8_t[]> var;
}

How exactly is the ctor handling the "move"? Is the ownership of the lvalue that the reference points to transferred to the member variable or is the reference another lvalue?
