Bob,

With all due respect I think the "or over the playing surface" deals directly with the leaping catch. I can't remember where I read it but I remember reading somewhere that the umpire is to try to line up the fielder's feet with the DBT when a catch is made. If the feet are completely in DBT(on ground or in the air) then it is to be ruled a foul ball.
