That's one of the confusing things about the App store. The app you purchase there is the Installer.
If you've successfully run the installer then your Mac is on Lion but the last step of the install proceedure deletes the Installer from your apps directory. The App store then reflects that the Installer is not installed on the system.. which is true.
You can redownload the installer from the app store if needed. If the installer is still in the Apps directory then you probably haven't installed Lion yet, just downloaded it.
