The same listing in the Google Play Store is used for both the mobile and TV versions of the app. Both app versions get uploaded, and Google decides which version of the app to install depending on the device capabilities.
For some reason that I've yet to work out, Google has decided that Android TVs are now capable of running the mobile app.
I'm currently in the process of releasing a new version of the Android TV app to the Play Store that will correct this. It can take Google a few hours to approve/release updates - I'll update here as soon as I've received confirmation.
