Why are there outgoing transaccions (yesterday and today) for about 0.6 eth from the pool address to addresses that have not mined or have a balance below the minimum payout if the pool has a 0% fee?. If that eth is all from miners below the thereshold, whats the point of moving it out of the pool address?, or i just missunderstood what prop means?

Note that Im new to this, and was just wondering why was that. In no way my intention is to start drama or w/e.
