The joke is that the syntax of Algol didn't actually look all that much like what people mean when they say "Algol-like syntax". No curly braces anywhere to be seen.
I could see that putting you in a place where encountering people misusing "Algol-like" to mean C-like, when trying to distinguish from something more like Algol, would be extra noticeable and annoying.
