This is not exactly relevant but I referred the final at the last Pacific Games tournament in 2011 in New Cal. It was not an Olympic qualifier though. My recollection was it was a tournament that OFC ran on behalf of the LOC of the Games and used FIFA statutes. They could not use the Games as a WC qualifier tournament because teams from outside OFC were present. Not exactly relevant in this case but OFC used FIFA statutes on that tournament. I guess the question you would ask is what set of criteria are being used for eligibility and whose take priority for this tournament. I believe the Olympics football tournament are run by IOC and not FIFA so would think their statutes would take priority.
Olympic events are contested under the rules and regulations of the global governing body of that sport, so it would still be FIFA statutes that apply.
