The one on the side isn't considered a drain as it doesn't completely drain the oil out of the engine. It's called the filter cover. The actual drain is under the engine. In the above video, they should have drained the oil out of the bottom first. This would have taken the swarf and sludge out with the fast flowing oil. Then the side cover should've been removed to access the filter screen for cleaning.
