I think the wording should be taken literally. It isn't that there actually are two selves, it's that there are considered to be two. Obviously on some level you know the selves are one and the same. The idea is: don't apply this knowledge within the thought process about whatever issue you're trying to decide. In other words, you can integrate / resolve all this knowledge into one cohesive whole (person X needs to decide whether to buy a new car, person X is me --> I need to decide whether to buy a new car; what should I do) or you can block that resolution process and proceed as if it is not yourself (person X needs to decide whether to buy a new car --> what should person X do).
