At times a lot of these can be classified as anti-patterns since the guidelines for how Bottom Sheets should appear are very vague. The purpose of a bottom sheet is to appear to be easy to reach for the thumb or index finger while providing an alternative to a popup or similar content accessible for taller displays and one handed use.
Essentially I believe it's an incorrect pattern since you're first travelling all the way on the top to tap on the overflow menu and then it also doesn't match the user expectation since people are used to the overflow menu opening in a different manner. The video you showcased doesn't allow the user to tap into the mental model of what they are familiar with.
