I think the point of this passage in the Ānāpānasati Sutta (MN118) is simply that you know the breath as it is. In other words, if the breath is long, you are aware of that fact, and if it is short, you know that.
You have perhaps also noticed that in the next stage of breath meditation (stage 3 in MN118) the verb sikkhati ("he trains") is added. The point of this is not so much that you use will-power to "experience the whole body of the breath", but that you train in understanding the causes for seeing the whole breath and then that you implement those causes. So sikkhati too does not imply an active control of the breath.
With metta.
