Yes, I echo the same comments as @zero9178. This doesn't look correct to me generally, a function being public isn't the only indication something can be referenced externally. Non-symbol callables could be called externally, so could symbols with their address taken. To be able to answer that question for symbol operations you'd need a deeper analysis of the program state (i.e. seeing what things reference the symbol and possibly how they reference it)
