You can grant privileges on a view ONLY if you have the same privileges on the underlying objects WITH GRANT OPTION.

What does this show? What does this explain? We don't even know the user that has executed the second part.

Normally a user can not grant access on one of their objects (bus_ui_v in this case) to another user if that object references other objects that belong to a third user (dual in this case as it belongs to sys).

The only way around that is to make use of WITH GRANT OPTION when granting access to the sys object.
You should read up on grants in the documentation.

That said - what is the point of this view?
And you should never grant insert/update/delete access to dual to anyone ever.
