I do wish you'd stop spreading incorrect information: pressure drag is
not just an artefact of flow separation.
(But then again, if you don't look at the diagrams shown in the cited videos, and numerous other ones that are available, you'd keep on saying that.)
But honestly, it's just such a basic mistake to keep on making.
