I don't think so.

Sure. You entered a number and then deleted all of its digits by pressing the backspace key. This leaves an "empty value" in X, i.e. a zero. The CLX function was not executed (because keeping the key pressed has NULLed it) so there is stack lift is enabled. However, pressing the backspace key has removed the last (here = only) digit, so all that remains is a plain zero.
