Please help with Mercurial Bookmarks workflow

Hello,

  I have been using local branches in git, maybe this breaks my attempts to master hg bookmarks...

  With Mercurial 1.2.1 I do the following:
1) create a repository (let's call it "repo1"), add a file "file1.txt" there, commit it
2) clone the repository (let's call this one "repo2"), add bookmarks extension and "track.current = True" under "[bookmarks]" to hgrc, create bookmarks "master" and "quickfix" there
3) at repo2: "hg up -C quickfix", change the file "file1.txt", commit it
4) at repo2: switch to master: "hg up -C master", hg out - and see that the changes to "file1.txt" are propagated into push.

  I expected that only changes to the branch I am on are propagated into push. Is it an expected behavior?

  I am not very proficient with Mercurial and sorry for any stupidity I have written.

  Thanks a lot for help!

Regards,
  Alexey
