I took the types to mean:
Type 1 = ski for fun most of the time, regardless of form/technique, terrain, or onlookers.
Type 2 = work on technique most of the time, paying attention to form/technique, terrain, or onlookers.
I didn't see any distinction regarding the skill level or terrain choice of either type, just outlook or attitude.
