Courtesy runners are for the pitcher and catcher, not John who is the pitcher or Jim who is the catcher. Therefore when Bob come in to PR he is neither a pitcher nor a catcher so he cannot be CR for. The CR is a positional substitution. If a player comes in on offense as a substitute for the pitcher or catcher they are only a pinch hitter and/or pinch runner and have not yet become the pitcher or catcher. That is exactly how it should be explained.
