How deep drilling(oil, etc) avoids drill twisting on its axis? Wouldn’t kilometers long steel drills be akin to licorice?

The drill string does twist on its axis. The drill string is akin to licorice. Good analogy and obviously it can withstand a little more torque than licorice.
When you stop drilling on the surface, the drill keeps turning on bottom until the licorice unwinds.
