Agree. You are asking git to change history depending on where pushes are done. Applying a legacy VCS paradigm here? Git has a global view of history. It must be the same everywhere, so if you push to two different places, the history must be the same, because those two places may in turn push to another shared repo. Then who is the authority?

What I have managed to do is to associated name and email with config --local so that it binds to the clone and overrides your --global setting. I can have different identities based on what clone I am working on, but once history is created, that's it. If I push from one clone to another, the identity of the clone where I did my first commit is what the second clone sees.

Hope this helps.
