The problem is that there's no real way to argue that X is not a reference to Y other than just saying it's  unlikely. Once someone believes that something is a reference or has a deeper meaning, it's really hard to prove them wrong, even if they don't have any evidence or compelling reason. I'd like to think the burden of proof is on the people trying to prove a connection, but from my experience, it's almost always my burden to try to disprove even the flimsiest connections. "It's a coincidence" isn't really a position that has supporting evidence though.
