Changing remote tracking branches in git(-svn) after clone with restricted branches

When restricting remote branches to a list of 2 or three (editing the .git/config as seen in {^1}), refetching, carbage collectioning and cleaning all "refs" directories I still get a full list of all remote branches with git branch -avv {^2}

I expected to see v2 and v3 only as branches in the list of remote branches. Any ideas how to fix this? Or is that the "git way" to present all remote branches either we might work with or not?

{^1}

[svn-remote "svn"]
url = https://example.com/svn/repos/MyRepo/SubPath
fetch = trunk:refs/remotes/trunk
branches = branches/{v2,v3}:refs/remotes/*

{^2}

* master         1234 [trunk: ahead 1] last msg master

git branch -D -r remotes/v1 remotes/v4 remotes/trunk
rm -rf .git/svn/refs/remotes/{v1,v4,trunk}
