There is a natural reflex/tightenening of ligaments when they have reached their full stretch. That reflex, when used correctly is very advantageous in performing a lift, especially a squat or clean.
The problem is when it is relied upon to be too great a percent of the power creation. If you miss the timing, you lose the rebound of the ligament/muscle and you're not strong enough to lift the weight on strength alone.
You might not be accustomed to this, which is why you felt a little pain.
To answer your question, the bounce out of the hole is common, and has its place. But make sure you are doing enough work with control the change in direction from a strength aspect.
