No, in the design this is the same entity. the **Patron** (who created the task) can (and usually _should_, probably) be different than the Arbiter/Escrow holder. There might be good arguments for optionally splitting out the escrow holder from the person who is judging the work. that could be a proposed change to the Catallax NIP - or perhaps a fork and we can let the market see which version does better.
