Purdy and El Salvador
There is a contradiction in the wording of WP:MOSFLAG. "Officially represented" is emphasized in the section titled "Biographical use". However, the section titled "Use of flags for sportspeople" says "...or has declared for a nation...". His sporting nationality will not be of any question on June 5. It really shouldn't be now according to what looks like pretty clear intent of the MoS so reverting is just wasting time.
