That "logic error" line is just a note to the developers and other
hackers.  

The client tracks the state of the TDS connection so that it can return
errors to the client if requests are made out of order.  (That also helps
avoid the server spanking us by dropping the connection for sending
invalid packets.)  In this case, the client is behaving correctly, but the
library isn't tracking the state correctly; somewhere we missed an update
to the state from IDLE to "sending query" or something like that.  

HTH.
