Perhaps the measurement is the total area INSIDE the hoop contrasted with the area actually reached by the strings outside the hoop. The difference on my TXE is about 1/4" in radius from the inside edge of the hoop to the actual outer loop of string(that is, the greatest area covered by the strings).
In round numbers: pi x 1/2l x 1/2w so...
pi x 6 x 4.5(inches) is approx 85 sq in
pi x 6.125 x 4.625 is approx 89 sq in
I think it's plausible to believe one company 'measured' from the outside loop of the string where the other measured the actual available hitting area INSIDE the hoop.
It's a stretch to call it a 'string area' vs 'hitting area'; but I don't think the ITF, ATP, NRA, USTA, MLB or any of the other alphabet organizations were in the loop when companies started talking about 'square inches'.
