The way the description reads:
"Allowed areas are defined areas you can assign to colonists. Colonists will not accept work or fulfill their needs outside of their allowed areas. Unless I'm reading that bolded part wrong, I would expect them to stay inside until otherwise allowed out.
The attached saved game was only to demonstrate what was going on. When I ran across this oddness was in a modified game where I was trying to keep the colonists indoors while a warg attack was going on (there's a bug with one of the mods where you can't lock the doors, so this was my attempt at a work around).
In that case, I had restricted them to indoors, where there was plenty of food items, bedding, etc. Their needs would of been met inside. Except, they went about their merrily way, going outside to harvest food, etc.
