That's not a problem with git. If anything it's an issue with github, but it's a pretty insignificant one IMO.
Yes, if you say you are billg@microsoft.com and make a commit to some repo on github, github will look up the username associated with billg@microsoft.com and show that user as the committer. Should it do that? Eh, probably not but this has come up a few times and github hasn't changed it. So by now we should just start to educate ourselves that this is how github is intended to work.
