From the good sense standpoint, putting two flow controls directly on a cylinder defies reason, which is not altogether out of the question under the circumstances.
A flow control on end A controls flow into A, and slows the piston movement away from A. However, when air goes in B, the flow control on A slows the escape of the air in end A, and this slows the movement of the piston toward end A.
Having another flow control on B is redundant, which you can say again, because it is useless. You will spend all day adjusting B, only to find A is still controlling it.
The only good way to control motion towards A is to have the flow control in the exhaust port connected through the valve to A. It will act only when A is exhausting, and won't throttle air flow in and out of B. Another flow control on the other exhaust port will not come into play until the motion is towards B, and this control will not affect A.
The pneumatics manual says on page 5 at the bottom "Always mount these into the ports of the cylinders before you hook up the tubing." This line is more intelligent if it is read, always screw these valves in before attaching the tubing(, because the don't swivel like the "L" push-in connectors).
Or perhaps the ports of the 'cylinder' is a transposition for 'valves'.
