I am wary of this kind of hidden state, which makes a command behave in 
two distinctly different ways. It is likely to increase confusion, 
rather than eliminate it.

It maybe could have worked if people called 'redo' before 'undo', thus 
creating a consistent indication of intent.

But the order is exactly the opposite, of course.
