The problem is that, that is the exact text used, well what you do is select a joint and then to transfer animation on to it via retargeting you need to have then skeleton's 'retargeting joints' the same.

As you can see the wildcard selections are just selecting a joint at a time, then the second part is exactly what comes up in the script editor if you have echo all commands on when you manually select a joint and do the command through the Maya UI.
