I made the following test. I built two colonizer and gave them kamikaze strategy. Then I put them in a fleet and gave the fleet a break formation strategy. I used the fleet to attack two escorts but the colonizers just went in the corners of the map and didn't try to ram. I tried using one colonizer without putting it in a fleet and it rammed without any problems.

I might be that when a ship breaks formation it doesn't get the strategy that was given to it. I think it gets the default strategy of the ship type. At least that is what happened to the colonizers in the test. What strategy those ships have that aren't misbehaving in your situation?
