That's not what that feature is designed to do. It lets you take all of the songs in one setlist and remove them from another setlist. Is it useful? Only situationally. That feature shows up when long pressing a setlist because it can also be used on the songs tab if you select a list of songs (where it makes a lot more sense to select a list of songs and then select a setlist you want to remove those songs from). What you are asking for is a "Clear Setlist" option. If you need something like that, i can consider it, but I'm curious how often you would use that. You could also just delete the setlist and recreate it, or edit it and then clear it in the group editor.
