B phrygian is the 3rd mode of the G major scale. They contain the exact same notes, but starting on a different note as the reference point.

G major scale:

g-a-b-c-d-e-f#

B phrygian mode:

b-c-d-e-f#-g-a

I cover modes here:

In particular you would use this pattern moved down 2 frets. Because this tutorial presents the modes of the major scale in the key of A major.

Does that make sense?
