You mean we're expected to know that Neapolitan is in reference to Naples (despite the ice cream not being from there) and doesn't relate to Napoleon at all?

Yes

A common reading comprehension error is people that have either been taught, or taught themselves to sight-read every word, and not just the super short ones. So rather than seeing what word is actually there for longer words, they see some of the more obvious or prominent letters and guess what the rest might be. And most of the people I know who learned that way never fixed it, no matter how big of a problem it became later. And it's like, a third of the people I know. Way more common than would be expected.

So yeah, those people will see Napoleon and Neapolitan and see pretty much the exact same word.

Can just be punny
