I add some edge test. And in the Integration Testing, the mysql client get the result:
mysql> create table if not exists `t1` (`id` bigint);
Query OK, 0 rows affected (0.00 sec)
mysql> split table `t1` between (-9223372036854775808) and (9223372036854775807) regions 1;
ERROR 1105 (HY000): Split table `t1` region step value should more than 1000, step -1 is invalid
