We want to change this message for clarity moving forward. It is preferred if we say something like "True in order to force a server refresh, false if the cached list is acceptable". The difference is minor, but it clarifies a lot in terms of what bps and paymentsystem are actually doing in the back end compared to the impression the documentation makes. Basically, if serverRefresh is true, it is absolutely forced, false will return a cached list if available (but it MAY still have to go to the server in some cases).
