It's implied in 22.A.7.C. because if you still had a freeze, you would be ineligible to bid for the new category without the exception for a new or reestablished category. By being eligible to be awarded the newly established category, Crew Resources has, in effect, ended any category freeze you might have. Further, 22.G.2 and 22.G.5 are the only places that expressly address a cumulative category freeze. Of course, those two sections also wouldn't apply to a newly established category. (You would just get a 24 month seat freeze for the initial qual training).
