That is correct, after doing the reset, the GS911 does not need to be connected while the adaptions are rebuilt by idling the machine
Reset of adaptions is a first step tool used by BMW techs when investigating problems such as rough idle, a BMW rep I spoke to last year was frustrated people did not understand the importance of reset/rebuilds, he recounted a story of running a test ride day and during the morning people reported one 1200GS was a bit of a dog, he had the tech with him run reset/rebuild at lunch time and the afternoon riders reported what a sweet machine it was, it is not the answer to everything but important when working on machines and replacing parts
