Missing STOPKEY per partition in Oracle plan for paging by local index

There is next partitioned table:

CREATE TABLE "ERMB_LOG_TEST_BF"."OUT_SMS"(
    "TRX_ID" NUMBER(19,0) NOT NULL ENABLE,
    "CREATE_TS" TIMESTAMP (3) DEFAULT systimestamp NOT NULL ENABLE,
    /* other fields... */
) PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255
  STORAGE(BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
  TABLESPACE "ERMB_LOG_TEST_BF"
  PARTITION BY RANGE ("TRX_ID") INTERVAL (281474976710656)
  (PARTITION "SYS_P1358"  VALUES LESS THAN (59109745109237760) SEGMENT CREATION IMMEDIATE
  PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255
  NOCOMPRESS LOGGING
  STORAGE(INITIAL 8388608 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1
  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
  TABLESPACE "ERMB_LOG_TEST_BF");

CREATE INDEX "ERMB_LOG_TEST_BF"."OUT_SMS_CREATE_TS_TRX_ID_IX" ON "ERMB_LOG_TEST_BF"."OUT_SMS" ("CREATE_TS" DESC, "TRX_ID" DESC)
    PCTFREE 10 INITRANS 2 MAXTRANS 255
    STORAGE(
    BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT) LOCAL
    (PARTITION "SYS_P1358"
    PCTFREE 10 INITRANS 2 MAXTRANS 255 LOGGING
    STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
    PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1
    BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
    TABLESPACE "ERMB_LOG_TEST_BF");

I have sql query, which select 20 records ordered by date and transaction:

select rd from (
    select /*+ INDEX(OUT_SMS OUT_SMS_CREATE_TS_TRX_ID_IX) */ rowid rd
    from OUT_SMS     
    where  TRX_ID between 34621422135410688 and 72339069014638591       
       and CREATE_TS between to_timestamp('2013-02-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss') 
                         and to_timestamp('2013-03-06 08:57:00', 'yyyy-mm-dd hh24:mi:ss')       
    order by CREATE_TS DESC, TRX_ID DESC
) where rownum <= 20

Oracle has generated next plan:
