The value is unused if I use operator overload

I have the following code, where Handle.operator-> is overloaded, readCount_ is a field in mirror::Object.

If I use this_object->readCount_, CLion reports warning "The value is unused".

  ALWAYS_INLINE T* operator->() const REQUIRES_SHARED(Locks::mutator_lock_) {
    return Get();
  }

If I use the code inside Handle.operator->, i.e. the Get method, directly, CLion no longer complains.

Why does using operator-> and Get make a difference?
