What if there were 3 cases though? "Else" should exclude both of the preceding cases, but the phrasing of "If not" seems to imply it would only exclude the previous case

True!

A point could be made for restricting ifs to 1 or 2 clauses and delegating more complex conditions to switch/case, but that is arguably even more far out there (and in case of Python it actually doesn’t have the switch operator). Also, “if not X {…} if not {…}” would be confusing but possible.

I guess I should leave language design to the better-equipped for the time being.
