It's unfortunate confusion, but a mistake from an employee is not a policy commitment. If Tim Cook said it, sure, but a low-level "representative" is just someone doing a job.
The company can delegate people to interact with the outside world and those people have the ability to bind the company. If they mess up beyond their pay grade then the company may have recourse on them but the company may well still be bound externally.
You still have to check if the functionary is an 'authorized agent' but if they misrepresent themselves as such then the company may well have a problem if you had no reason to believe otherwise (for instance: because of their job title or because someone with signing authority delegated the interaction with you). Such 'apparent authority' (of which this may well be a case) is the source of much confusion and many lawsuits.
This is why, until I see a transcript of the conversation, I'm extremely inclined to believe this is the developer giving the best possible interpretation for their cause. I've spoken to Apple people and they are good at all this stuff in my experience, they know what they can say and what they can't, they're careful, and they're non-committal. Marketing people encouraging us to get our app on the store were still deferential to App Store Review and always reminded us they had the final say, and wouldn't be pinned down to any specifics.
