I'm reading that as the instructions for if you have an itinerary that includes 2 star alliance carriers rather than as a requirement to have 2 *A carriers. To me this page doesn't address single airline tickets so it doesn't appear to exclude the extra bag for *G benefits for single airline situation.
No, its from their check in baggage page under the "Number of bags included in our fares" heading. It says nothing about connecting flights.
