CleverPin's autoreactivate pass code feature?

I have no clue on how to use this feature, I did some research but I did not find anything explaining how to use it.
What I did so far is, obviously, create a passcode. I set it to immediately ask me for a passcode. Then in CleverPin, I set it to autoreactivate my passcode after an hour. What I think this feature does is that if I leave it inactive for too long, it'll reactivate my passcode. So I added my wifi to the whitelist, left my phone alone for an hour, then slid to unlock, and CleverPin skipped the passcode...

Does this feature actually do what I think it does? And how do I actually use it?

Thank you!
