Issue:
The unload job was executed for the  first time  with these options: REMEMBR=YES, UNLOAD=ALL, and it produces the following message:
DBG73109I DSN 12:35:36 DATA COLLECTOR POSTED TO REMEMBER POSITION 
It was executed again with these options: REMEMBR=YES, UNLOAD=NEW, and this message was produced:
DBG73109I DSN 12:52:08 DATA COLLECTOR POSTED TO REMEMBER POSITION 
The generated reports for the two runs were identical with the same data.  Why the same reports being produced?
 
Resolution:
Executing the unload the unload process manually caused the problem. Executing the unload process automatically using the offload percent parameter resolved the problem.
