I think they made the changes. I once had such an "over the counter" sim card but later changed to a monthly contract with my passport. But I remember seeing on the expat magazines "last chance to keep your SIM card active". At one point you had to provide ID or they just turned off the service.
That's not hard to do in China (well, your SIM card would be China Mobile or China Unicom, not T-Mobile), unless they've made some drastic changes in the last couple of years. But since I've seen the claim that you had to provide ID to buy a SIM card made at times where I knew it was currently false, I strongly suspect it's still false.
