That's not a rule but a special compromise. [[ ]] and (( )) are a form of reserved words themselves just like () and {} as they can be used multi-line but they aren't allowed to be adjacent to else et al without a semicolon. [[ ]], (( )), {}, and () are practically just commands with first-class parsing that consistently have to end with
a semicolon if followed by another reserved word or command.

I'd call it less a compromise than a mechanism; of all listed,
{} represents a block of code in the current shell, () represents
a block of code in a subshell...

but if you want to go down that track, it's kind of interesting to note
that {} on a single line demands a ; before the }, while () prohibits
it. This also seems inconsistent to me, but not at the same level of
egregious brokenness as select.
