To see the command line that results after word splitting, replace
this with:
  tail session_log |
   for arg in \
    gawk -v Username=`basename $i` -v TodayDate=`date '+%b %e'` \
      -v CurrentYear=`date '+%Y'` -v BlockFlag=$blockflag \
      '$0 ~ /[Uu]ser/ && $0 !~ Username && $0 ~ TodayDate \
      && $0 ~ CurrentYear \
      {print Username, $0 >> BlockFlag}'
   do echo "$arg"; done

I suspect you need to double-quote the command substitutions and
variable expansions.
