Yes, that means I can be an agent for escrow transactions that I know about. I am able to validate transactions, but not just any transactions, for no matter who. I first need to know that person, to see if there's not scamming involved, to be announced beforehand about the conditions of the transaction, etc.
Maybe you misunderstood how escrow works all together...
@ashaman explained it to me, I had zero knowledge and didn't know that I have to inform you beforehand.
