No, well I say no, its not how he teaches positioning. We had four positions for the front lights throughout the day:-
1. High key shots of model on the floor, they were at waist height pointing square on, no tilts forward at about 45* in each corner if you like.
2. With the group shots, we raised one high updirectly behind the camera in the centre of the shot, then the other up to about shoulder height, again at the same angles above.
3. On the Black background, depending where you wantd the light only one was used and it was at the side of them waist ish height as she was sitting down.
4. One light directly above her to achieve the effect it the last of my pics.
The hair lights were very high up at the back pointing basically to where ever you wanted on the head/hair.
