Um, no. Just plain no. Even on tapered threads, the thread form is still perpendicular to the axis of the part. This thread form is perpendicular to the taper, so it's not a proper thread profile and won't seal.
When making BSP thread, the cutter is perpendicular to the spindle axis But the purpose of the video is to make the ABI thread and the cutter is perpendicular to the taper
