I read of a similar method to the article a few years ago. Use a regular drip brewer with 50% of water normally used (by weight). Place an equal weight of ice in the jug. Brew as normal to get tepid or cold coffee in the jug. Add more ice after you pour or add milk. What I read said the results tasted better than simply pouring over ice because of the process of dripping the hot coffee over the ice as it brews gives a different flavour than simple diluting by adding ice later. OP's article seems to support that and I found that to be true - it works very, very well and it's very simple.

As you say, the aeropress method is basically the same as diluting at the end by controlling the strength of the brew and I'm not sure it will work the same way.
