mload with NOSTOP option ends with Return Code 4

Hello,
In my mload script i have the following:
0037 .IMPORT INFILE xxxx
        FROM 4
        FORMAT  VARTEXT '^\'NOSTOP
        LAYOUT &load_table.
        APPLY Inserts;
The multiload skips the errors and inserts the records which respects the conditions

     .       Highest return code encountered = '4'
I have no other errors except the rejected records.
 
If i use tpump with NOSTOP option the return code is 0
My question: Is this the normal behavior of multiload and tpump if we use NOSTOP option?
I was expecting for both (mload and tpump) to have the same behavior and to finish with Return Code 0
I'm running on TD14.10
 
Thank you,
