If you KNOW that the LEAF does NOT "use" the Proximity Detection, perhaps you would be kind enough to tell us.
Otherwise, we can easily test, plugging in an un-powered EVSE and check if the LEAF will move. I believe "DarkStar" reported earlier in this thread that the car does NOT move.
Ok, just to be clear - you want ME to dig thru the manuals to cross-check how the Leaf responds to the existence of the L1/L2 connector even though we both know that you have the same manuals I'll spend my time digging thru?
That's fine. It'll have to wait until later today though.

Leaf Service Manual
From J1772, the EVSE-side connector has three signal paths - the two AC wires, the pilot signal, and the proximity signal. As Gary already mentioned, the proximity signal is powered from the car, not the EVSE. The proximity signal also includes the push-button on the L1/L2 connector.
From the Service Manual, Section C (electric power train), chapter VC (vehicle charging) page VC-10, the car supplies +5V to the proximity function. I cannot find an indication that the +5V is always present.
Service Manual, Section C, chapter EVC (EV Control) page EVC-32: When the driver operates the power switch while depressing the brake pedal, the car activates the systems and goes to the 'READY' state - except when the charge connector is connected.
I haven't yet found when the car sends +5V to the standard charge connector. This is required for the car to detect the presence of inserted charge connector. It may be safe to assume that 5V is present when the car is on or in accessory mode, but if it was my car and my insurance policy, I'd want to know for sure.
I'd certainly use at least two wheel chocks regardless.
