Default Logic II Aristotelian Sorites

I have a question on the validity of AS. If AS are arguments made of 4th figure premises and made of "All" statements (Barbara's which is not a valid categorical syllo in 4th fig.) and validity depends on the validity of its component syllogisms, why are they valid being made up of "all" statements.
