Why is the difference relevant? The shafts were me matched based on the frequency measured along the same plane (stiff or soft), and since the spine is identified, the shafts will also be aligned in the clubhead in the same manner. We could argue the benefits of which orientation is best for spine alignment, but the by identifying the spine first, and then using that identification to both measure frequency and later assemble clubs, the variation in frequency at different shaft 'clockings' doesn't matter. As long as the spines are all aligned identically, the frequency slope used will be valid.
