This seems like an inconsistency in your arguments. The "on Tuesdays" clause is imported,
but the "by its owner" clause isn't? They're serving exactly the same syntactic purpose
in exactly the same structure.
While they may have the same grammatical function, they have an
important semantic difference:
For the "by its owner" case, there is always some entity that CAN
perform the action by announcement, so the action CAN always be
performed by announcement, so R478 gives conditions under which persons
perform the action.
For the "on Tuesdays" case, there is sometimes no entity that CAN
perform the action by announcement - this means that it is false that
"the action CAN be performed by announcement", so R478's clause says
nothing about when the action is performed.
