It only happens on else branch of IfGruard expression, where a given var is none. Original a seem to be still in scope.

fn main() {
	aaa := ?int(none)
	bbb := ?int(1)

	if a := aaa {
		println("aaa: $a")
	} else {
		if a := bbb {
			println("bbb: $a")
		}
	}
	if a := bbb {
		println("bbb: $a")
	}
}
