If you delete a branch in svn, the "content" is still there in the sense that it is there in previous revisions. You only delete a pointer in your svn-filesystem. In git, a branch points at a commit, and deleting a branch means making that commit pointerless (unless it is pointed to by other branches or tags). So far there's some similarity. But now, if that commit and all its descendants are "pointerless" (can't be reached from a named ref) git will garbage collect them after a while. They're considered pointless ;) svn records the rename as a copy+delete (it also sets some rename info which git-svn seems to ignore). So, git-svn stays on the safe side by keeping the branch. Note that deleting the branch would possibly delete at least some info since the branch name is not recorded in the commit (if you use svn.noMetadata). You can safely delete the branch if you're sure its head commit is contained in some other branch (as will be for an ordinary rename).
