This has nothing to do with either the "Don't get hurt" strategy or resupply. All ships are either attack ships with "Optimal weapon range" strategy or missile armed carriers (loaded with fighters) with "Maximum weapon range" strategy. They are not all in the same fleet. In fact a number of them are not in a fleet at all. There is a resupply base in the system that they are in. Ever time they get low on supplies, they go back to the resupply base. Then they return to dance in front of the warp point. They never enter the sector of the warp point to engage the colonizer in combat.
Every once in a while, some minister decides it needs one of those ships for something else and it leaves through a different warp point. Other attack ships enter the system on some appointed task and get stuck at the troublesome warp point, thus joining the dance, resupply, dance, resupply cycle. Once they are in the cycle, their standing orders are cancelled at the end of each move so I can't see what it is they think they are trying to do.
It was funny to watch for the first 20 turns or so.
