Shifting could have been called 'sliding' as there is usually a guide finger touching the string during the shift. However some shifts also involve 'jumps' where we have too large a distance and too little time to slide.
Playing harmonics is a good way to practice 'picking the note out of the air', since we get instant feedback as to whether we have hit the correct note, because harmonics either sound clearly or not at all.
Notice that Fintan uses the same finger for the same pitch, you can also practice this with changing the fingers, for instance playing the top note with a different finger every time.
This exercise will help you develop your knowledge of fingerboard geography.
