Well your thinking is right the wording is wrong it takes two copy's of the same gene to be expressed. A pastel is really a het super pastel, so a pastel is to a super pastel what a Het hypo is to a Hypo..
A two gene animal is something like a Bee (spider Pastel) or a King pin (pinstripe Lesser)
See the difference..
you'll get it just hang it there
