Here's a variation on Marshall's approach. I've excluded from the output all lines tagged '(could be removed)' in the desired output shown here. 

c:\@Work\Perl\monks>perl -wMstrict -e
"my @cleared = (
   'JOB::HEREISASTRING',
   'Something',
   'StringA',
   'StringB',
   'StringC',
   'StringD',
   'Something Else',
   'StringE',
   'StringF',
   'StringG',
   'StringH ',
   'JOB::HEREISANOTHERSTRING',
   'Something',
   'StringI',
   'StringJ',
   'StringK',
   'StringL',
   'Something Else',
   'StringM',
   'StringN',
   'StringO',
   'StringP',
   );
 ;;
 my $rx_job = qr{ \A JOB:: [[:upper:]]+ \z }xms;
 ;;
 my $rx_thing = qr{ Something | Something \s+ Else }xms;
 ;;
 my $prefix = '';
 CLEARED:
 for my $clear (@cleared) {
   if (my ($pre) = $clear =~ m{ \A ($rx_thing) \z }xms) {
     $prefix = $pre;
     next CLEARED;
     }
   ;;
   if ($clear =~ $rx_job) {
     print $clear, qq{\n};
     next CLEARED;
     }
   ;;
   print qq{~~$prefix~~$clear\n};
   }
