What steps will reproduce the problem? 1. Set bzr backend 2. Edit document A three times, now rev is 4 3. Edit document B one times

What is the expected output? What do you see instead? Rev 2 is expected for document B But Rev 5 is found.

Please provide any additional information below. http://en.wikipedia.org/wiki/Comparison_of_revision_control_software says that only cvs is not of atomic commit. So I think all current backends to the same thing for whole document set.

This is the intended behaviour. All documents are versionized in a single repository so there are globaly unique revision numbers.
