Incorrect setState usage in example

https://reactjs.org/docs/hooks-state.html#equivalent-class-example shows

render() {
    return (
      <div>
        <p>You clicked {this.state.count} times</p>
        <button onClick={() => this.setState({ count: this.state.count + 1 })}>
          Click me
        </button>
      </div>
    );
  }

However, https://reactjs.org/docs/state-and-lifecycle.html#state-updates-may-be-asynchronous provides the following examples, indicating that we should not use this.state.count + 1 when updating state dues to async updates:

// Wrong
this.setState({
  counter: this.state.counter + this.props.increment,
});

// Correct
this.setState((state, props) => ({
  counter: state.counter + props.increment
}));
