Probably. But the real question should be "is it meaningful"?
I wonder if the "lines of code" take into account the submittal of hundreds or thousand of lines of translations of interface text, for example.
E.g., Pieter merges a dutch language file and gets several thousand lines of code added to his "stats".

Edit, P.S.: see for example https://github.com/bitcoin/bitcoin/commit/b1f031d43520825c9288dfbfb410b0065e6732a6
