No, the 4 million figure of iPhone 4S was a direct sales number to the consumers. The 9 million "preorder" of Galaxy S3 were the orders by the carriers and retailers worldwide prior to the launch of the phone, which is actually very clear in the original Korean articles.
Thanks for the correction. I still haven't found the original article by The Korea Economic Daily (why can't they link it?) but Reuters make it pretty clear that the 9 million number are orders from distributers, retailers and carriers.
It's a shame that other occidental publications simply call them "preorders" without specifying those are basically units to be eventually shipped, not units customers have actually preordered.
There's no point calling them preorders at all, they're just orders from whoever will sell them. That would be like saying the iPhone 5 already has "50 million preorders" just because that's the number Apple expects to ship to Apple stores by the time the iPhone after is released.
The article doesn't even specify a timeframe for those orders. The original Galaxy S is still sold by many carriers who probably still get new shipments of them, over 2 years after its release.
