I guess if they actually had HVAC vents under the seats feeding cold air, it might cool you off more quickly blowing it up through the seats.
If the AC is doing its job, you shouldn't need seats to draw the air to you. I can't see how this design could in any way be superior to the seats pushing the air and using those types in Florida heat I can tell you that the temperature of the air was never an issue.
I wonder if it has more to do with keeping the perforations in the leather intact... thinking that pushing air could force the edges of the pores to raise and rub against you entering/exiting the seat and eventually mess up the leather, where as pulling air in keeps those edges downward when running. That's my best guess.
I'm interested to see if OP tries to mod.
