I assume you do this because you believe that it may help find a better move as
opposed to solely searching from the root position?  If so, aren't you making
the overall search deeper but also more selective?  And hence your own chess
judgement is important?

Looked at another way, if "stepping in lines and then retracting" can give a
better root move, why doesn't the search from the root do this automatically?
Maybe it's the user's chess skill that is a key factor?!
