Correct. This is a classic security vs convenience tradeoff. I mention that trade off on the landing page, PanicLock vs Shutdown

> Use shutdown when you can, PanicLock when you can't. Shutting down is the most secure option—but when you need your Mac locked now and you'll be back in five minutes, PanicLock is your answer.

*PanicLock* - Fast "oh shit" button - Lid closed when in transit. - Instant lock (1 second). Disables Touch ID immediately - Preserves your session - Back to work in minutes

*Full Shutdown* - Maximum security - Purges encryption keys - Fully locks FileVault - Takes time to shutdown & restart - Kills your session

Better than nothing and keeps them from having unlocked access. You can do it fast in your pocket.
