To be pedantic the line is actually thru the point on road about which wheel turns; not always directly below kp. I am not sure about the meeting at diff gudeline but as explained the outer wheel does more work so the rim is more turned than the contact patch, esp with crossplies. So wheels are arranged to stay more parallel than Ackerman ie the outer wheel turned more then theoretical.
