I take it you want to know intuitively why the partial and simple autocorrelations could have opposite signs. Consider the following fictional scenario. In a given town, people get fatter as they get older. As a consequence, their doctors recommend that they exercise more. So older and fatter people exercise more than young, skinny ones. The correlation between weight and exercise would be positive simple correlation. But if you adjust for age, you would find that those who exercise have lower weight than those that do not exercise for a given age.
