Sorry, I misread the log. Please disregard my last comment.
Tags aren't versioned in Bazaar (like in Git, but unlike mercurial and Subversion which do version tags) so when pulling from another branch it is not possible for Bazaar to see which branch was modified later, just that they are different. If there is disagreement over what revision a tag points at, the local tag isn't changed and a tag conflict warning is printed.
