Git used to have much sharper edges than Mercurial, but that is
pretty much a thing of the past. With Git you pretty much can't
permanently lose history unless you try really, really hard.
It'll always be there in the reflog for a period of several days
minimum (I think 2 weeks by default?) and if you're worried about
it you can configure it to put that off for months or years...

On the other hand, I have had Mercurial bugs repeatedly lose work
of mine. The kind of bugs that aren't easy to reproduce so nearly
impossible to report and nearly impossible to fix. The ecosystem
of "extensions" makes this problem inevitable. You depend on
extensions, typically third-party extensions for the first few
years of their life, for all of the power-user stuff, and the
extensions have as much power to corrupt or lose history as the
main library does. And of course, they have the potential to
alter the behavior of the core library making reporting bugs that
much more difficult ("ok, but which extensions, official or
unofficial, do you have installed?"). Now instead of one team
writing bugs you have N teams writing them in isolation.

Combined with their failure to accomodate the distributed
development model properly you now have a bunch of incompatible
ideas for managing branches and history editing and they still
haven't gotten it all right yet (but they're getting closer the
more and more they model the design after Git).

The user name and email fields are not controlled in either Git
or Mercurial so anybody can commit code under your name without
you being involved. That would be pretty unprofessional though...
I can't imagine Git magically pulling your name out of nowhere
when it looks up the author of commits that are responsible for
lines of code... Maybe you should report that to the mailing list
and get to the bottom of it... I suspect that the explanation has
nothing to do with any bugs in Git.
