No, if you omit the argument then it defaults to the context node.

I see now where your problem lies. generate-id() produces a unique ID for
the node supplied as the argument. It knows nothing about nodes in the
output document. If you generate two nodes in the output from a single node
in the input, then generate-id(.) will produce the same value twice.
