I'm not very good with paint, but here is what I mean. Say the barrel is 1 and where the tshirts are is number 2. Assume that both tshirt tubes are filled and have something in them. The shirts would not be able to move. Assuming they are relatively packed in the barrel, they will let air through, but it will not be instant and it will expose the assembly to the full pressure.
