I believe that a wire is rated by the total cross sectional area of all it's strands. If one wire of the same gauge uses 10 strands and another uses 20 strands, the one with 20 strands will result in a smaller overall diameter. The smaller individual strands pack together tighter and there is less wasted space between strands. This could account for the reason two wires were rated the same but different diameter.
