Python Selenium driver keeps old data after click

Question

I use Python Selenium to grab Youtube Video URL. I load the home page first and I click on a random result. Form that second page, I want to get the suggested video on the right. But when I do that, the driver just ADDS the suggested video to the list of video found on the home page. I don't know why... so I need to reset or clear something inbetween find_elements

driver.get('https://www.youtube.com/')
time.sleep(8)
items = driver.find_elements(By.XPATH, "//a[@id='thumbnail'][@class='yt-simple-endpoint inline-block style-scope ytd-thumbnail'][contains(@href, 'watch?v=')]")

for i in items:
    url = i.get_attribute("href")
    print(str(url))

rand = random.choice(items)
rand.click()
time.sleep(10)

# GET SUGGESTED VIDEO ON THE RIGHT
yt_right_pane_items = driver.find_elements(By.XPATH, "//a[@id='thumbnail'][@class='yt-simple-endpoint inline-block style-scope ytd-thumbnail'][contains(@href, 'watch?v=')]")

for i in yt_right_pane_items:
    url = i.get_attribute("href")
    print(str(url))

The OUTPUT of the HOMEPAGE:

The Second output = Videos of the first find_elements + videos of second find_elements

On the second find_elements, I only want to get the NEW video form the page that was clicked on.
