From what I remember, that's probably the lessons where Anders is using the Maj and Min pentatonic scales.[br][br]So he's showing you how to move between the major and minor pentatonic scales whilst keeping the tonic note the same.[br][br]e.g.

You can play A min pentatonic starting with your index finger on the 5th fret of the low E string. You are playing the pattern/scale on frets 5-8.[br][br]If you shift your fretting hand to the left so that you are now starting with your pinky on the 5th fret of the low E string and play the same pattern on frets 2-5 then you are now playing A maj pentatonic.[br][br]It's the same fretting pattern but the position of where the tonic A falls in the pattern changes, which changes the intervals relative to the tonic and hence changes it from min to maj.[br][br]HTH
