agreed that extracting this adds clarity, but isn't this functionally equivalent? The lambda makes sure this get bounds to the parent scope from this.render() call, which should be the React-component. What am I missing?

They are functionally equivalent. The change is that the original code created a new function on every render. The new code uses the same function reference on every render. This is important because down stream DrawControl componentDidUpdate will get called every time any of the props change. This means that even though the function is the same, componentDidUpdate gets called because the function reference has changed.
