Flask: How do you redirect to the same page with the same address, but with different content?

@app.route("/login", methods=['GET', 'POST'])
def login():
    if current_user.is_authenticated:
            return redirect(url_for('admin'))
        else:
            return redirect(url_for('home'))

@app.route("/admin")
def admin():
    return render_template('admin_home.html')

@app.route("/home")
def home():

    return render_template('home.html')
