The fingering used in the previous example is only one possible fingering for the Blues scale in this tuning. In any tuning, there are many possible fingerings for whatever type of scale you are playing.
When you learn a new tuning, it is worth experimenting with many different fingerings for scales in that tuning. This is an enjoyable way to explore the tuning as well as being good ear training and helping you find your own favorite sounds and fingering patterns.
