It might be better for “rolling” veins.

If you surprise the vein, it won't have time to roll 🤣🤣🤣🤣

The speed at which the force of the needle is being applied, at the time of breaking the tension of the skin and vein, could very well impact/mitigate the subsequent movement of the blood vessel.

I’m not sure why suggesting that the physics involved may be helpful for rolling veins, is apparently so ludicrous.
