What is the use case for this weird switch mecanism

I've no idea why it's authorized, but it saved my day a week ago, in
an automatically-generated switch statement that happened to have a
"return true;" inserted at the very beginning. No unit test found that
and I saw it only by printing the generated code for another search.

In a way, it's logical: the code path jumps to the matching case, so
it never sees the first statement block before the first case.
