This is a dummy example because the cache is destroyed at the beginning of the script ! So the first case of the if statement is impossible.

What leads you to believe that the first branch of the if statement is impossible? What if another script running concurrently has inserted a document with that ID in between the call to remove and call to get?

It's worth noting that if you saved a cache file with a group, you *have* to provide that group to remove it. (The group is part of the hash used to store it.)
