'Undo' Handicap

I was recently thinking about a new form of handicap. It works like this:

The weaker player have the option to undo his very last move for i.e. 5 times, but he cannot use his benefit twice for one move.

What do you think about this form of handicap? Is it instructive? Or can it create a bad habit of 'undoing'?
