Apparently it tries to be smart and guess the appropriate topic. The relevant function is [1].
As far as "safe" goes, I think it is. This is only the Gerrit topic, not target branch, so the worst that happens is that pushing a new changeset will actually change the topic on you. You can always force a topic with the -t flag if you really don't want that to happen for some reason.
Git review has their own bug tracker, mailing list, etc. if you feel like tracking this down further, but I'm not too concerned at the moment. Good catch though.

Would it try to push it to a different branch on gerrit? Or would the Change-ID being the same prevent that?
