Then, the move constructor of MyClass is called when std::invoke executes, which passes that rvalue to threadFunction<1>. Copy-only On the other hand std::thread t2(threadFunction<1>, std::ref(obj)); // <-- calls only copy The thread stores a std::reference_wrapper...

Again, the overload rules work such that the move constructor is called only for a temporary object--and only a temporary object that can be modified. One thing this means is that if you have a function that returns a const object, it will cause the copy constructor to run instead of ...
