See below:

werner@X10DAi:~/Public/repo/github.com/OrderN/CONQUEST-release.git$ git log --author="JianboLin" --stat --summary origin/f-mlff | awk 'NF ==4 && $2 =="|" && $3 ~/[0-9]+/ && $4 ~/[+-]+|[+]+|[-]+/ {s+=$3} END {print s}' 8519 werner@X10DAi:~/Public/repo/github.com/OrderN/CONQUEST-release.git$ git rev-list --author="JianboLin" origin/f-mlff | git diff-tree --stdin -r --numstat --no-commit-id | awk '{ s += $1 + $2 } END { print s }' 8519

So, your method and my original one give exactly the same result. Therefore, I can't see what their fundamental difference is.
