I believe that only gives a list in iOS 10 (at least it doesn't give me an option to select it in iOS 11, just shows me the number of apps I have), and I believe it's a list of just the 32-bit apps that are installed.
I select it in 11.1 B5 and get an "App Compatibility" list showing the currently installed apps that don't work under 11, i.e. they're 32-bit.
Edit - simultaneous post to iSayBoourns, who is correct.
