Aside from a silly youtube example, can you provide a case where this could happen in planning stages? As I see it, you anticipate some ensemble of possible scenarios for each possible action, and you can weigh those ensembles against each other. The ‘go back and try again’ is just part of that, but if one of them says ‘go back and try again’ and aims at something you’ve already done, you can use the precomputed result and move on to something else.
