No, what you get are "double hets". Because these traits (like albino, patternless
and blizzard) are not allelic (that is, different versions of the same
gene) they sort independently (or we assume they do). Because of this,
an animal can be "het" for albino AND "het" for blizzard and it will
look "normal."

The key is that both parents DO have "normal" genes. The
defective gene that causes albinism is "normal" in a blizzard
leopard just as the blizzard gene is "normal" in an albino (which has
a defective albino gene). The traits are independent of each other.
I hope this helps.
