In this application of small, lightweight, "low mileage" vehilcles where tire-life and turning perfomance are not life-and-death issues, the steering geometry is felt to be "good enough." One tire or the other scrubs a bit and the turn is not as precise as it could be but it's not a big deal.

In order to get the correct Ackerman Geometry with the steering linkage in front of the axle the tie-rod ends must extend out past the king-pin (pivot point.) Thus with the linkage behind the axle you can have angled-in steering arms but in front of the axle they just be toed-out. This puts them actually inside the wheels themselves, which is even more problematic in setting up the steering in our models. So we generally make due with "good enough."
