Is it true Nissan can do this with two lease returns but only one new lease?

I have two Nissan leases ending around the same time, but I'm only getting one new Nissan lease.

I heard NMAC's $395 disposition fee waiver is basically 1-to-1, so I'd still owe the fee on the second return.

Has anyone successfully avoided this by having the dealer buy out/trade in the second lease instead of returning it to NMAC? Or is it better to ask the dealer for an extra $395 discount/credit on the new lease to offset it?

Has anyone actually negotiated this with a Nissan dealer?
