The left wristcock motion is a perpendicular motion from the impact alignments (flying wedges)- up and down. Therefore the more turned that the grip becomes - the more that the wristcock motion turns into a wristbend but its still geometrically flat to the plane of the left wrist motion (left flying wedge). It is perhaps most preferable to have the grip set as such that the wristcock is truely flat so that it can be monitored easier.
