Where does it say this?

This occurs when one canopy is flying directly in front of the other, also known as a "stack". The nose of the rear canopy will tend to "lock" into the front canopy lines. NEVER cut away the main canopy when it is in front.
First, ensure that there are no entanglements. Take the time to LOOK! Trace all 8 risers to see they are clear, up to the sliders, and visually follow the lines up to each canopy. The risers could be entangled; you must look up and follow each riser to make sure they are all clear of one another.
DO NOT release the brakes.
If the canopies or risers are entangled (this can happen if the reserve fires through the main canopy through deployment), or you are at less than 1000', or you are unsure, then steer the FRONT canopy, very gently, using the Rear Risers. Canopies of similar size will fly compatibly. Try to prevent a down-plane.
If the canopies are not entangled, you can use the rear risers on the REAR canopy and steer into a side-by-side configuration. Then follow the information above for a side-by-side.
When landing, DO NOT flare, and be ready to perform a PLF. The descent rate of two canopies out is slower than if you are under a single canopy.
