rknikko... which edition of the NEC are you referencing? The 1999? Or an earlier edition?
In the 2002 and 2005, Article 334 is NM cable and Annex E is used to identify building types, Annex F is a cross reference to Articles in earlier editions. In the 1999 NEC Article 334 was for MC and there wasn't an Annex F.
I'm not seeing that wording you referenced in any recent NEC. But, I didn't go back any farther than the 1996 NEC.
BTW. The Annexes (or is that Annexi ) are found in the back of the NEC. But, in reality, I assume you knew that.
Hope this helps.

Type3= (combination of combustible & noncombustible)
At the risk of being called a nitpicker I would point out that the usual description of type three construction is "Ordinary Construction, Masonry bearing walls with wood floor and roof assemblies." It is also often called "brick with wood joist" by firefighters. -- Tom H

Building construction types are explained in the current building code adopted by the jurisdiction of question. Where NFPA 220 Table E is similar to the IBC which is adopted in many areas, I would advise that assigning building types in a specific area be in accordance with the local building code. ( if your jurisdiction has adopted the NEC there is no guarantee that the building enforcement branch has adopted table E of NFPA 220).
Type I and II structures in general do not have any wood framing members, with the degree of flammable interior determine the degrees of each type. As mentioned Type III is generally a masonry envelope with standard 2 X, 6, 8, Construction
Type IV is Mill Construction Stone or masonry exterior with Heavy timber interior (Plank floors etc.) Type V is a typical (for the NE anyway)wood frame dwelling.
