In Revised, the Indian IC pretty much always was a bad idea, as Japan could simply react on it on J1.
Unless playing minor victory (which is better balanced than major victory), wherein an Indian factory is essential.
And to get back on topic: I think the key difference here opposed to Revised is that in AA50, UK moves after Japan.
If Japan moves away from India, going for the China or Russian route, it might be very liable to buy an Indian IC at UK1.
In some ways, Japan going first hinders the Indian factory. If UK went first, they might actually get to build in the IC before Japan can capture it.
