Why do we need to type `template = 'user_stream.html'` if there has been `template = 'stream.html'` ?

In the flask course, when we want to create a stream.html to show either our or others' own social network page, why do we need to type template = 'user_stream.html' if there has been template = 'stream.html' ? I thought that when we type template='stream.html', we have already tell the program to go to stream.html. Can someone help explain the following code from the course the teacher wrote?

And what is the template='user_stream.html' stuff? This is the first time it showed in the course but lack of explanation. Thank you!

@app.route('/stream')
@app.route('/stream/<username>')
def stream(username=None):
    template = 'stream.html'
    if username and (username != current_user.username): 
        user = models.User.select().where(models.User.username ** username).get() 
        stream = user.posts.limit(100)
    else:
        stream = current_user.get_stream().limit(100)
        user = current_user 

    if username: 
        template = 'user_stream.html'
    return render_template(template, stream=stream, user=user)
