It's the same joystick design. As the video says that doesn't mean it will have the same issues as frequently, but it does mean it can have the same issues. The question will be at what rate.
Given the coverage I have very low hopes that we will get a good idea of that from the press. Instead I expect the first Switch 2 joycon to drift will be put on an auction sale for every clickbait article to parade in front of people with rotten tomatoes at the ready. Still, it will matter if it's one in two or one in a million.
