I believe the expiry date is built in (Ex. 364 days remaining) that's why they're playable offline. Once this date is skipped they'll be automatically locked unless Ps+ is renewed. It is unsure what happens though when online servers are completely shut down and a PS+ membership becomes redundant on the console.
