The majority of most detergent additives is solvent. You could have a detergent additive that's blended to meet the EPA minimum that waters down the actual detergent more than a more highly concentrated additive in less solvent.
As for what they're trying to achieve:

Although EPA's minimum detergency requirements are beneficial, they do not satisfy the needs of all vehicles. Many oil companies have chosen to provide more than the minimum required amount of additive. These include some small, independent marketers as well as some major marketers, and these marketers often advertise their fuel's improved detergency. Unfortunately, many consumers may not be aware of which fuels have better detergency. Even with that information, however, most consumers are not able to evaluate the claims made by marketers.

It is important to note that the absence of a gasoline marketer from the list of TOP TIER Detergent Gasoline participants does not necessarily mean that the marketer is using only the minimum EPA-required amount of detergent additive. For one reason or another, that marketer may simply have decided not to participate.
The reason why the automakers care is that they get a lot of people bringing in vehicles for warranty issues because they're sluggish, there's poor fuel economy, and most importantly because of emissions issues. They're the ones driving it, and they're not making any money from setting up the Top Tier organization.
