Using the latter is problematic as if you don't copy the return value before calling Format again your formatted message will be overwritten by something else. This bug was observed in m_callerid where InspIRCd::Format was being used for formatting two arguments the latter of which was being overwritten with the former. We could have preserved the return type and just copied the string but then callers would have had to deallocate the string once they have finished with it which is an undesirabable burden to put on callers.
