Always be wary to cover your own licence. Any ambiguity then cover yourself regardless of what the book says. Do not descend unless instructed to do so which is what I learnt on opposite end deps against arrs. Be careful I always ensure we can descend before doing so but that is me and due to a nasty experience. There are many idiots out there especially the ones who write the books but they are not the ones in the seat at the time. Happy flying.
