I haven't looked into it for a LONG time, but USS messages are sent on the (real or emulated) SSCP-LU before any BIND has been processed. The BIND contains the "extended datastream" flag. Before there has been a positive response to the BIND VTAM (or the Tn3270 server pretending to be VTAM at USS processing time) does not know that the receiver can handle extended datastreams and the receiver does not know that it should handle extended datastreams. Therefore, the USS data uses the most basic datastreams available. That being said, I have no idea what happens if the USS data is an extended datastream. VTAM and Tn3270 servers probably send it. If the receiver processes it without first being told it should, then everything probably works.
