It means reversal of a previous policy. By itself there is nothing wrong with it. If you find in practice that your policy proves to have weakness it makes all the sense to change direction. If your driving along and you find out your made a mistake do you persist with that mistake? I should think you ought to make a about turn as soon as possible. Ultimately it's not about u-turns but about the final destination. If you manage to make success then that is all that matters even if you made 99 u-turns along the way.
On the contrary if you make no u-turns but your destination is a bankrupt, debt ridden economy like Nawaz left then I would say that is a disaster.
