It is based solely on the fact that those who originally drink soda (loaded with calories), then switch to diet to "lose weight", are largely making poor decisions with their food choices and nothing more.

So, you mean to say, that if you artificially force certain parameters on the dieters you can get the results you want?
Brilliant!
In real life, though, secondary impacts of things such as the impact of a particular food on overall diet actually matter.
Here's an example from 2011:

For one study, researchers at the center followed 474 diet soda drinkers, 65 to 74 years of age, for almost 10 years. They found that diet soda drinkers' waists grew 70 percent more than non-drinkers. Specifically, drinking two or more diet sodas a day busted belt sizes five times more than people who avoided the stuff entirely.

The other study may hold the answer. In it, researchers divided mice into two groups, one of which ate food laced with the popular sweetener aspartame. After three months, the mice eating aspartame-chow had higher blood sugar levels than the mice eating normal food.

And here's one from Silock's site of choice, although it's a bit older (just wanted to point out that pubmed has both sides, as well):

Adult male Sprague-Dawley rats were given differential experience with a sweet taste that either predicted increased caloric content (glucose) or did not predict increased calories (saccharin). We found that reducing the correlation between sweet taste and the caloric content of foods using artificial sweeteners in rats resulted in increased caloric intake, increased body weight, and increased adiposity, as well as diminished caloric compensation and blunted thermic responses to sweet-tasting diets. These results suggest that consumption of products containing artificial sweeteners may lead to increased body weight and obesity by interfering with fundamental homeostatic, physiological processes.
