I believe the lights used in the example (particularly the Profotos) were due to the wide spread assertion that they are immune from color shift as power is changed. The point is to show those lights don't have as consistent color as "common knowlege" would dictate, but have the same color vs. power profile as any other voltage controlled flash (including the Alien Bees and White Lightning).   
Color temperature on the Einstein does increase in Action mode. A comperable chart can be found in the manual here:
