Question for EC: Deceleration

From your latest blog in regards to deceleration…

Slow-speed, Full Stop, Hold > Slow Speed, Full Stop, Acceleration > Slow Speed, Quick Transition, Acceleration > Normal Speed, Full Stop, Hold > Normal Speed, Full Stop, Acceleration > Normal Speed, Quick Transition, Acceleration

Open-loop > Closed-loop (predictable > unpredictable)

I was wondering if you could talk a little more about this, with what do you use these progressions? During lifting exercises? Or, for example, would a wide receiver use these to practice his routes?
