I may be being obtuse, but a competent lawyer will see right though that...
Given the grammar ambiguity the title of the bullet/callout "nomenclature has changed" adds to the possibility to interpret it either way, much clearer would be "function has changed".
Another try to minimize difference ?
Accurate description is "EITHER switch will deactivate both"
