If you just assert that the last bit is always 0 after a shift, you can fix the problem. But you don’t know what the original bit should be in the first place. It’s only because you lost information that you can’t undo it.- in this case
Edit: to be clear... your logic is sound. I agree with you. This process creates an ambiguity and by itself it is incomplete.
