That doesn't make sense does it? Vacuum in the chamber still draws fuel through the pilot jet just less of it hence why a car can tick over with no throttle. Think of all of the two stroke motorcycles in the world surely they would all seize the first time you rolled down a hill if this was correct?
Is it something to do with the mass of the car being able to pull the car at a higher sustained rpm for longer?
Two strokes have a much lower compression ratio, are you thinking about that being the freewheel feature, as the engine braking is a lot less noticeable.

The freewheel feature was, IIRC, due to some Saabs having a two-stroke, and therefore as lubrication is part of the combustion process with those, if you drive the engine with the wheels, no lubrication is happening = boom.
