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.
