Perfectly natural; that's why most of us do it late at night under a
blanket in the closet with all the lights turned off :)

Technically, the revision is no longer in the _branch_. It's still in
the _repository_, because uncommit doesn't actually delete anything.
But it's no longer part of the branch history; anything looking at
that branch would never know it was there.

Then (after your uncommit) that 'far' branch would have the rev, but
your local branch wouldn't. To push later, you'd either need to push
--overwrite (to tell bzr it's OK to discard that rev from the farside
branch), or get that rev back into your local copy to push (e.g., via
merge). Of course, that latter would defeat the purpose of
uncommitting in the first place...
