Yes, everyone either modifying or distributing (=submitting) the patch
should add their s-o-b.

Correct. When you do a git pull you are pulling the commits without any
modification, so technically it's not even possible to add the s-o-b
lines to the commits you are pulling. Modifying the commit logs would
need a rebase and then it not would be a normal git pull anymore.
