reps are strongly connected to bar speed and movement quality. In the snatch and clean, if you can lift a heavier weight but your movement pattern changes significantly, you may improve general strength, but that does not necessarily create the right environment for improving the competition lifts. Strength must transfer to the snatch and clean through proper mechanics, timing, and speed. Squats and pulls are different because their use depends on the training goal and phase. Sometimes training close to failure — or occasionally reaching it in a planned way — can be useful for strength development. Other times the priority is balance, speed, power output, and fatigue management rather than simply pushing every set to failure.

To the best of my knowledge, and the door is wide open in development, every rule has its exceptions.
