The "git checkout" command executed could fail if, for example, upstream contains a file that would overrwrite a local, untracked file. The output redirection didn't work as stderr was redirected to /dev/null, as was stdout. This appears to be not what was intended so the order of redirections is fixed so that stderr is redirected to stdout instead.
