It's because you are using anonymous functions. When an anonymous function passed or executed it has a unique ID associated with it. Irrespective of how many times you use the same anonymous function it will have different ID. A named function tends to preserve its ID with means it can be fetched my the screenfull.off function and then background process can act on it.
HINT: screenfull.off inherits all from element.removeEventListener which means it works the same!
