With the damper system and the sostenuto system properly regulated, the only way an engaged sostenuto note can get below the blade is by releasing the sostenuto pedal, if there is a broken tab, or if the tab is loose. If there are other ways, I do not know of them at this time. Please keep in mind this thread is about a Steinway sostenuto system which I am only addressing.
