It sounds to me as though Scipio wasnt the host, when he launched his ww, his client program executed a deceleration, but the host is needed to 'create' a new ship (the ww). A glitch in the connection somehow delayed that from reaching the host and it took the scenic route. A short while later, the host registered the launch of the ww, and then acted accordingly, accounting for why Scipio all of a sudden slowed down again, and the ww was launched.
