This still seems a strange approach. Generally, it is good to make methods as functional as possible - in the sense that we should generally avoid updating parameters within methods.

In this case, the process being performed by 'SetTotalPrice' doesn't meet the requirement of being an expected result. The method describes setting the price, but not the fact that the operation affects the value of the customer.

Consider moving some of the behaviour into another method or class, representing the process as a whole.

If the whole thing is to process an Order for example, so 'SetTotalPrice' calculates the total price, then the part to deal with Points and Roles should reside elsewhere, and the process of updating them should be part of, for example, the ProcessOrder method that in turn calls SetTotalPrice.
