Raider 2.0 "Triple Progression"?

Raider 2.0 calls for "triple progression" on some of the isolations movements, but describes double progression. (It tells you to read the FAQs, but doesn't mention this at all in the FAQ).

Am I missing something or did BOM use the term wrong in the program, given that Raider 1.0 just uses double progression? I can't really tell because alot of his content has confusing errors.
