This is fairly typical with exe uninstallers. Essentially, the exe is just a bootstrapper that launches another process to perform the actual uninstallation and then exits right away. ConfigMgr does not know (or really have any way to know) that this is what is happening so when the bootstrapper exits, it thinks the uninstallation is done and it performs the detection. Of course the actual uninstallation is still going on so your detection method will probably still show the app as installed meaning that the uninstallation failed.
The best way to handle this is to add a script to your package that first calls the uninstaller and then pauses for a handful of seconds to account for the spawned process that actually performs the uninstallation (the uninstallation is usually pretty quick so 5 seconds should suffice but ymmv so test). Then, run this script as your uninstaller. You could potentially get fancy and try to detect the process and wait for it to exit in your script but that's a lot of work for no real gain in functionality and where a simple pause works well enough (ConfigMgr could try to do this also for that matter but they never will as it's a lot of work for a minority use case).

I have an application that is installing correctly however when I go to uninstall it using the Software Center it uninstalls correctly but the Software Center reports that it has failed. It's using its own uninstall .exe to remove the software and my detection rule is using the presence of the applications .exe to determine if its installed. (It doesn't use MSI technology, looks like install shield or something similar) When the uninstall.exe runs it kicks off the uninstall process however it returns an exit code 0 (success) straight away in the AppEnforce.log. Then App deployment detection runs immediately after this exit code is registered and because the application's exe is still present it thinks it hasn't uninstalled. It eventually fixes itself up after an Application Deployment Evaluation cycle is run which then picks up that the exe is no longer present. The problem really lies in my detection rule however I'm not sure what options I have. If anyone has encountered this sort of issue before and has a possible solution I would be interested in their thoughts. I'm thinking I need a script maybe that will loop until the uninstall.exe has finished removing the application??
