Video Player - Is this .bind() statement really necessary?

Link to Video Player project at:
https://www.codecademy.com/paths/web-development/tracks/front-end-applications-with-react/modules/react-102-stateless-inherit-stateful-u/projects/video-player

In the 3 files I post below, I can see that the .bind() statement is necessary for the chooseVideo() function in the App.js file because it is called in a differenct component. (The Menu.js file, in the handleClick function)

But, in the Menu.js file, we are told the handleClick() function must use a .bind() to bind it to the Menu class component. Yet, the handleClick() function is only called within the Menu class component. It seems that this .bind() is unecessary.
Am I worng?
Thanks,

File: App.js:

import React from 'react';
import ReactDOM from 'react-dom';
import { Video } from './Video';
import { Menu } from './Menu';

const VIDEOS = {
  fast: 'https://s3.amazonaws.com/codecademy-content/courses/React/react_video-fast.mp4',
  slow: 'https://s3.amazonaws.com/codecademy-content/courses/React/react_video-slow.mp4',
  cute: 'https://s3.amazonaws.com/codecademy-content/courses/React/react_video-cute.mp4',
  eek: 'https://s3.amazonaws.com/codecademy-content/courses/React/react_video-eek.mp4'
};

class App extends React.Component {
  constructor(props) {
    super(props);
    this.chooseVideo=this.chooseVideo.bind(this);
    this.state = { 
      src: VIDEOS.fast
    };
  }

  chooseVideo(newVideo) {
      this.setState({
      src: VIDEOS[newVideo]
    });
  }

  render() {
    return (
      <div>
        <h1>Video Player</h1>
        <Menu chooseVideo={this.chooseVideo} />
        <Video src={this.state.src} />
      </div>
    );
  }
}

ReactDOM.render(
  <App />, 
  document.getElementById('app')
);

File Video.js:

import React from 'react';

export class Video extends React.Component {
  render() {
    return (
      <div>
        <video controls autostart autoPlay muted src={this.props.src} />
      </div>
    );
  }
}

File: Menu.js:

import React from 'react';

export class Menu extends React.Component {
  constructor(props) {
    super(props);
    this.handleClick = this.handleClick.bind(this); // I think this is unnecessary. It is not
  }								  // by any other component.

  handleClick(e) {
    var text = e.target.value;
    this.props.chooseVideo(text);
  }

  render() {
    return (
      <form onClick={this.handleClick}>
        <input type="radio" name="src" value="fast" /> fast
        <input type="radio" name="src" value="slow" /> slow
        <input type="radio" name="src" value="cute" /> cute
        <input type="radio" name="src" value="eek" /> eek
      </form>
    );
  }
}
