It goes off the plane to got from the last video. is not on the plane, because we have This vector will be perpendicular to the plane, as the normal vector n. So you can see here thar vector n and pseudovector d have the same direction but not necessary the same magnitude, because n could have all the magnitude, on the contrary, the magnitude of d is fixed by the magnitude and the dircetion of f. So given that d and n have same directions, and n is not FIXED (it's a vector), the angle is the same, sorry for my English, hope it will help you. You may well get more acceptable results like this.
