Duplicate name only works with link that has image attached to it. This is because internally, they are always referenced by the internal node object. However, link without images are referenced by its name from the node group input and so duplicate name won't work:
(Notice we have three '1' links but they all connect to the same input socket).
For now, it isn't prohibited to generate a Beantextures node group with duplicate link names. However, a warning pop-up is displayed when the user attempts to do so. I guess this is a valid way to say that the user may get "undefined behavior" with their generated node, but regardless, it'd be more elegant to have a consistent behavior.
