I treated this private object Disposed as a private "token" similarly to DisposableHelper.DISPOSED in Rx itself (they have the warning there "don't leak it"), but here I didn't do compareAndSet(Disposed, ...) because comparing to initial null was enough, so I think your change is correct.

Yep. Just trying to save APK size anywhere I can by reusing existing stuff.
