Loop in a Loop with index less than the stopped one

I have the following problem and I need an idea how to overcome?
I have 2 identical ITABs: ITAB1 and ITAB2 with 60 records.
I am looping in the 1st ITAB and when I am finding a record I am looping in the 2nd ITAB with INDEX = sy-tabix of the 1st one: 

LOOP at ITAB1 where COL = '001'.
  lv_tabix = sy-tabix.
  * Do STH.
  LOOP at ITAB2 FROM lv_tabix
    * do sth
    EXIT.
  ENDCASE.
ENDCASE.

Lets suppose that I am looping the 2nd ITAB with lv_tabix = 17 and, I am exiting from the 2nd when its tabix=22.
So I am returning in the 1st ITAB do sth and, I am starting the loop of the 2nd ITAB with lv_tabix=21.
I have noticed that the loop of the 2nd ITAB cannot start from a record (21) which is less than the one it was stopped (22).

Am I right?

How can I overcome this problem?

Thanks
Elias

Cannot reproduce your problem.

DATA(table_1) = VALUE string_table( ( `A` ) ( `B` ) ( `C` ) ( `D` ) ).
DATA(table_2) = VALUE string_table( ( `A` ) ( `B` ) ( `C` ) ( `D` ) ).

LOOP AT table_1 INTO DATA(row_1).
  DATA(start_index) = sy-tabix.
  LOOP AT table_2 INTO DATA(row_2) FROM start_index.
    IF row_2 = `C`.
      EXIT.
    ENDIF.
  ENDLOOP.
ENDLOOP.

works fine, although in the first outer loop iteration it exits the inner loop at sy-tabix = 3 and in the second outer loop iteration restarts the inner loop with the lower start_index = 2.
