I like it, Clement. However, the highlighted term as written means that 2 is true in the set of cells r5c5 and r8c7. You've proved, and need, that 2 is true in both cells. You should write it:
(4)r2c1 = r2c9 - r3c7 = (4-2)r5c7 = (r5c5)&( r8c7) - (r89c5, r8c45) = r9c4 - r9c1 = (2)r7c1
I also wouldn't describe it as a net. It's a nice split-node AIC.
