Lease Return - same tires required?

This car came with the Pirelli Scorpion run flat tires. Dealer tells me at the end of the lease (2yr/20k miles), if these tires are worn, I will need to replace them with the same make and model. Is this true? The sticker for this car just says "All Season Tires" (vs my GL450 which actually said "Mercedes Extended Mobility Tires"). Dealer claims there is a "secret list" of tires which will work but he can't tell me which ones -- doesn't make any sense.
From what I've read these tires will not make it to 20k miles even with rotating them every 5k miles.
Thanks in advance for any help! I'm in the Southern California area.

The only advice the sales guy gave me is to look for used tires on eBay or whatever of the same make and model when its time. Based on my research, these tires will not last 20k miles even with regular rotations and my sig other driving it and she is not an aggressive driver at all.

Also, if the car had run-flats, I do believe that they are required at lease return as the 2020s don't come with a spare tire (unless specifically optioned that way).
My suggestion: Run the RF tires for about 10k miles. See how they are wearing, and if you think you'll need new tires before lease end, assess at that time. If everything looks good, go another few thousand miles and check again. Just stay above 4MM at the lowest point (not including the treadwear indicator bumps). There is absolutely no point worrying about it now...
If you do have to buy new tires, and decide to get non-RF, store the original tires and put them back on shortly before returning the lease. I did this exact thing with my 2014 BMW, and it worked out fine. I bought a compressor kit with a bottle of fix a flat at Wal-Mart, and never had to use it. Put about 15k on the RF before changing them out, and another 30K on the tires I bought, then swapped them back at 45k for the lease return.
FWIW, this is EXACTLY my plan with my 2020 GLC with the Continental Run Flat tires.
